This lesson covers the identification and characteristics of even and odd functions, focusing on their graphical representations and symmetry. It explains how to graph polynomial functions, describes the symmetry of these graphs, and distinguishes between even and odd functions based on their exponents. The lesson also discusses the behavior of functions as they approach infinity and provides examples to illustrate these concepts. Students are encouraged to use symmetry to determine function types and are given homework instructions for further practice.

What is the primary goal of lesson 3.3?

• To recognize and distinguish even and odd functions

• To learn about linear functions

• To study trigonometric functions

• To understand quadratic equations
