Talk:Graph of a function

I don't think this is a very clear explanation of graphing polynomials. I think the general idea of a graph should be shown instead; explaining what a graph is (representation of f(x) vs. x), instead of having a tutorial of graphing polynomials, since the graphs drawn by these tutorials won't be really accurate anyways. What does everyone else think? Myself 01:23, 13 August 2006 (EDT)

How would you draw more accurate graphs? How accurate do the graphs need to be? What is the purpose of drawing a graph? Certainly we can't use graphs as evidence in a rigorous proof. Graphs provide a visual way to look at functions and allow for conjectures about them as one use, right? I don't see why we should take out the tutorial on graphing. Certainly please add any additional info you think is pertinent (like f(x) vs. x).

I just don't see how useful knowing what a graph is if you can't draw one. --Joe 11:07, 13 August 2006 (EDT)

Using we in mathematical writing

It's ok to use the first person "we" in mathematical writing (this isn't english class :P ). Here are some references: here and here. You can just leave the page how it is for now. --Joe 11:27, 13 August 2006 (EDT)
