Graphing Polynomials: Finding X Intercepts

This video tutorial teaches how to graph polynomials by finding X intercepts. It explains the importance of X intercepts, how they relate to the graph's factors, and the role of sign changes. The tutorial addresses common misunderstandings, such as the impact of squared factors, and guides viewers through the process of graphing by testing intervals. By the end, viewers will understand how to determine the graph's shape and direction based on the zeros of its factors.

Describe the process of determining the sign of a polynomial in the intervals between its X intercepts.
