Exploring Even and Odd Functions

The video tutorial covers the concepts of even and odd functions, explaining how to identify them by substituting negative x into the function. It provides examples to illustrate these concepts and discusses the types of symmetry associated with even and odd functions. The video also includes practice problems and a recap of the key points.

What happens to the function f(x) if it is an even function and you substitute -x for x?

• The function remains the same.

• The function becomes undefined.

• All signs change.

• The function becomes zero.
