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.
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

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?
