Graphs of Polynomial Functions

Published on 10/20/2009

Activity Overview

The activity begins by having students compare functions to introduce the concept of end behavior. Then they graph cubics and quartics, noting the respective end behaviors for positive and negative leading coefficients. Finally, they compare quadratics to quartics and cubics to quintics to discover that the degree of the polynomial also plays a role in end behavior. They conclude the activity by summarizing their findings.

Before the Activity
