Understanding Zeros of Polynomial Functions

This lesson covers the concept of zeros in polynomial functions. It begins with a review of polynomial expressions and the definition of functions. The video explains how to evaluate functions and find zeros by setting the function equal to zero. It also addresses common misunderstandings about finding zeros and demonstrates the relationship between zeros and graph x-intercepts.
