A polynomial graphic tool

The Java applet below will help you to graph polynomials, and much more.
Here is a summary of its features:

At all times, the location of the active nodes will be displayed at the current resolution, which is also displayed. The current resolution is the width of one grid interval.

The way you write a polynomial is like this: x^3 - x + 1 or -2x^2 + 1. In the current version of this tool, the coefficients must be integers.

We could tell you more, but if we have done our job correctly you will be able to figure things out for yourself.

A known bug is that you zooming several times rapidly in succession may freeze the display temporarily. So zoom slowly.
