thanks I'll try it tomorrow. But I think I got an easy fix by using smaller intervals in x incremented by 0.1. The graph looks nicer but I am not sure that it's mathematicaly correct.

cant see the picture? http://www.hobojjr.yurx.com/graph2.jpg What do you mean by restrict the range? How do I do that?

I am not sure that it worked... Look at the picture... I did what you suggested and it just drew a small graph..

yes I did and I am trying to implement it as we speak

no I am a nerd... This is just extra feature for the project.

sorry didn't read what you said... from 1 to 2 it will make points (x=1,y),(x=1.5,y),(x=2,y)... don't see how it would zoom in or out.

nothing... it just makes more points

well I just go over a loop and plot points... for(x=-10;x<10;x++) { y=a*x^2+b*x+c; point(x,y); }

can you explain in more detail please?

Uhg... I don't know how to explain this... I have a function f(x)=aX^2+bX+c I want to plot point (x,f(x))--i know how to do that I want to be able to zoom in/out the graph--need help here here is an example http://www.analyzemath.com/quadraticg/quadraticg.htm click the start button under...

no... what is the math behind the zoom? I am writing a program. Do I just divide the whole thing to zoom in and multiply to zoom out?

Now I am trying to graph this thing. Lets say I have x^2+x+10=0 So yah... I plot them for -10<x<10 and get the y values... What I would like to know is how do I change the scale as to get zoom in and zoom out effect?

And how is this different? This guy is making money from it as well... hypocracy?

Do the chickens have large talons?

someone explain
