hmmmmmmmm........ a graph is something we use to represent an increase over a period of time..... or something like that...... we use it to show increase or decrease in information........... but what is really a graph for...... I have no idea...... wasn't my favourite topic ;-P
Well yeah...a graph shows a change...whether it be an increase or a decrease.....this change is represented by the gradient....and well as for the x-axis and y-axis...they can represent anything....i think it's like....ummm...say...the change of something on the x-axis....with respect to the change of something on the y-axis......not sure
but one thing though, if it is change with respect to each other...... then what if one axis does not change........ what then? Is it still a graph?????
Yea a graph is a representation of change.It shows increase as well as decrease of anything.However, change does not have to take place in both axes.If change does take place in one axis it is still a graph.
so wait I know we use graphs everyday and I know a little on how to do graphs but I still don't know why we use it......... I mean if there wasn't graphs what would we use???? if it had an alternative.....
Yeaaa...now realise that...when there's no change in one axis....there cud stil be changein another....but then at that point....but then...let's say the x-axis increases while the y-axis remains constant...the graadient(change in something) will be 0......daz not of some significance....?
I would like to know that same thing original_dapper17....... it must have some meaning to it........ otherwise what is the sense in using it anyway....... it could be replaced with something more simpler because for me, graphs doesn't click in my head....... it is like chinese to me......lol
Lol....daz why we here...to help each other....to make that chines understandable...:P Lol...anyone willing to shed some light on the significance of the gradient being 0 at that particular point of a graph where change occurs in one axis and not the other....i know when change only occurs in the y-axis it is said to be infinite.....but how come....?
hmmmm that is a very good question but I wish some other people could help us too because we would need alot more heads in this to figure stuff out...........
yep its just not used in exams only, and i realised it could be in many different forms, e.g. of a line joining points plotted between coordinates, or a series of parallel bars or boxes, there may be more too..
ok I understand that much but I still sticking with my question....... why??? Is there anybody who think they know the answer...... even the slightest.......
well as i understand that the use of a graph is 2 represent in a pictorial way change of something which we can make desigions from it an derive information easy.
yea..having a pictorial display would make it sooo much easier 2 read and calculate info...i mean..u think..what would be easier..watchin a bunch of numbers on paper or actually drawin it out..graphs are just 2 make things simpler 4 us..
My assumption is that...judging from the formula of calculating gradient...to allow for a gradient you must have a change in both axes...since m = y2-y1/x2-x1 and, if at a particular point in the graph change is only occurring on one axis then there will be no gradient at that point...hence gradient = 0...(to answer part of original_dapper17's question)...this of course is only my assumption
When change occurs in the y axis the gradient is undefined...a change in only the y axis would mean a straight up or down line...which means there's no change on the x axis...hence x2-x1 for gradient calculation would = o...and anything divided by 0 is undefined
well I hope graphs makes things easier but for me, graphs not my thing...... it still confusing..... I like maths and I could work good with the numbers and letters but when it comes to the pictorial graphical thing...... it just confuses me.... and I understand what it is used for and what it really is but I still dont know why we use it.........
wel a graph is represented by to lines,a horizontal line which is the x axis and a vertical line which is the y axis.a graph can only be plotted if there r points,but in real life its one quantity against another.for eg.there r those time vs acceleration graph where the speed is constant but as miss says we r human and no one can be in dat position 4long.newaz...without graphs then scientic wouldn't be able to mak so much discoveries and they would'nt be famous 2day lol... hmmm..wat can i say abt graphs again....any1....i'll hav to get bac wit u on dat 1
well I think Desi Girl said it all and I think I understand why we use graphs now......... and a graph is a pictorial representative of information with 2 sets of values where one vs the other in a scaled mapped out designed to show the quantities of each values as it rises of drops......... I think........
I think a graph is a visual representation of the relations between certain quantities plotted with reference to a set of axes... graphs don't always mean one quantity against another, as we what we normal work with...as miss was explaining...global positing system, there are 3 axis (i think) i believe its longitude against latitude against time...im not to sure(this is whats in my head no hating please)...but do correct me if im wrong...but otherwise that graph would be drawn in 3D...which might be a challenge for some of us if given to draw..thank god 4 technology...lol...
i think you can have the 3 axes and they do use it for 3D stuff because x-axis and y-axis is 2D like up and down but what if you wanted to go in and out then the z-axis would be used. they use graphs to make life easier for use you can predict vaules and find vaules using graphs when drawn to scale and remember in class when we were doing logs and some questions can only be solved using graphs .....well then it just proves that graphs can solve for values when equations sometimes can't do the job ....
graphs as everyone already said that graphs displays information, that i agree with but one graph i think is very usefull is the line graph and is used everyday in businesses it displays a chane of a quantity with respect to chang in time, i think this is one important type of graph followed by the normal pie chart etc.
I think everyone already covered wat i think, but i need the 10 marks, so i'll say it again ne how. i think graphs represent a change in sum quality with respect to a change in another quality, in picture form, which makes it alot easier to read and interperet the data. After all it its much nicer watching a curvey line than watchin a page full of numbers.
graphs do make our life easier actually...i think the purpose is to depict a relationship between two things...like if we were to look at the distance time graph in physics...it shows the relationship between distance and time. the relationship cud be seen by the type of graph drawn. whether its a curve or a straight line o whatever the case may be. We also know that distance / time gives velocity but with the graph we need not have the trouble of calculating the velocity since it cud ber ead off from the graph
graphs give an idea of what is going on with something. like if you wanted to know the output of a process during a particular time period, you can use a graph plotted process output to time and see where you have high outputs and low outputs. you can even use the graph to see where a problem may have occured in a process.
miss cud u plz post a new question, or cud someone ask a question plz because everyone is writing the same thing over and over and im not learning anything new.
i think a graph is really a visual comparison! it compares two different things and it clearly shows changes such as an increase or decrease or afluction ect...
To answer for animechic and IQ200..basically from my understanding of a graph is the idea of relating a pictorial representation of information by two quantities, the x-axis vs the y-axis..
Using a graph and its purpose is really to make life easier by predicting the rise and fall in real life values of situations...than one having to use numbers and counting forever to get to a value that they want to correspond to...
A graph is a visual, concise means of presenting information it help in understanding relationship between the figures on the vertical axis and those on the horizontal.
a graph plots the value of the variable at a specific point, then connects the dots in order to give you some idea of the relationship of consecutive points. graph may also be used to show how the value of a variable changes over time. For example, if you are doing an experiment about the number of people in a certain mall, you might be interested in the number of people in the mall at a certain time, but you may also be very concerned with the trend of the population. Is it increasing or decreasing?
a graph makes it easer to see relationships on paper.when i think graphs i think about gradient, i think change.for me graphs make it alot easer to relate real world problems on paper, so it makes it easer to be seen.
A graph is a visual representation of two or more variables (like time, temperature, distance, etc) shown with respect one another. Theses variables are arrange in a specific order (such as being on a "y" or "x" axis) all being referneced to the point 0.
The types of change usually involves either an increase or a decrease of the variable....
for example financial cpmpanies often looks at pattern involving an increase in profit with respect to time. This increase is an example of change which is gradient in real life form...
i understand graph are used for numerous things such as checking your height growth with respect to time(age), so in other words as your age increases so does your height
Why not allow our creator, Jesus, to show His love? Make Him your best friend by telling him the things you tell your best friend. When Jesus is part of your everyday life, well you are on top of the world. The best things will happen and the trials will be testing but the best for you will prevail.

ReplyDeletehmmmm that is a very good question but I wish some other people could help us too because we would need alot more heads in this to figure stuff out...........
ReplyDeleteI guess it's probably cause of how the line will keep increasing vertically with no end in sight it's siad to be infinite....idk...??
ReplyDeletewell yeah...... there are an infinite amount of numbers so I guess the graph can be infinite to and its values.......
ReplyDeleteso its a diagram showing relationships between varying quantities
ReplyDeleteyea basically but it is used for so much more........... that is what we have to figure out........ why????
ReplyDeleteyep its just not used in exams only, and i realised it could be in many different forms, e.g. of a line joining points plotted between coordinates, or a series of parallel bars or boxes, there may be more too..

ReplyDeleteA graph is a representation of two things.
ReplyDeleteexample it can be used in a business to represent different months of year when there was an increase or shary decrease in stocks
A graph is a visual representation of two or more variables (like time, temperature, distance, etc) shown with respect one another. Theses variables are arrange in a specific order (such as being on a "y" or "x" axis) all being referneced to the point 0.
ReplyDeleteWhen graphs are plotted, it often represent a change. This type of change is known as the gradient and can be found by the formula........
ReplyDeletey2-y1/x2-x1
Simply stated as change in y over change in x
The types of change usually involves either an increase or a decrease of the variable....
ReplyDeletefor example financial cpmpanies often looks at pattern involving an increase in profit with respect to time. This increase is an example of change which is gradient in real life form...
i understand a graph to mean, the comparing of one thing with respect to another.
