This algebra lesson explains some important rules about zeros (where graphs touch or cross the x-axis).

This algebra lesson explains how to find the absolute maximums and minimums (extrema) of a polynomial.

This algebra lesson explains how to find where a polynomial is increasing, decreasing or neither.

Find out how to find relative minimums and maximums of the typical polynomial.

A java applet that lets you graph a first degree polynomial and see how changing the coefficients changes the graph.

Given a polynomial, determine the intervals at which it is positive or negative. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
