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.

What is a polynomial function and how can it be expressed?

Explain the concept of a function in terms of input and output.

What changes can be made to a function while still maintaining its definition?

How do you determine if a given input is a zero of a function?

Describe the process of finding the zeros of a more complex function.

What is the relationship between the zeros of a function and its graph?

Summarize what you have learned about zeros in polynomial functions.
