In this lesson, we will use the above features in order to analyze and sketch graphs of polynomials. We will then use the sketch to find the polynomial's positive and negative intervals.

In this unit, we will use everything that we know about polynomials in order to analyze their graphical behavior. Specifically, we will find polynomials' zeros (i.e., x-intercepts) and analyze …

This topic covers: - Adding, subtracting, and multiplying polynomial expressions - Factoring polynomial expressions as the product of linear factors - Dividing polynomial expressions - …

Challenge problems on graphs of polynomial functions and their behavior.

Learn how to manipulate polynomials in order to prove identities and find the zeros of those polynomials. Use this knowledge to solve polynomial equations and graph polynomial functions.

Zeros are the x values at which the function is equal or the polynomial, in this case, which is a function of x, is going to be equal to zero, and you can see that's happening exactly four times.

In this article, we'll learn how to determine the intervals over which a polynomial is positive or negative and connect this back to the graph.

When we are given a polynomial in factored form, we can quickly find the polynomial's zeros. Then, we can represent them as the x-intercepts of the polynomial's graph.
