Even and Odd Functions Analysis

The video tutorial explains the concepts of even and odd functions, focusing on their symmetry properties. Even functions have y-axis symmetry, while odd functions have origin symmetry. The video demonstrates how to test functions by substituting negative x and analyzing the resulting function. If the function remains unchanged, it is even; if the signs are opposite, it is odd. Functions that do not fit either category are neither even nor odd. Examples are provided to illustrate these concepts.

What type of symmetry do even functions have?

• Origin symmetry

• X-axis symmetry

• Y-axis symmetry

• No symmetry
