Description
In this lesson, students use the factored form of polynomials to identify important aspects of the graphs of polynomial functions and, therefore, important aspects of the situations they model. Using the factored form, students identify zeros of the polynomial and see how to sketch a graph of the polynomial functions by examining what happens between the 𝑥-intercepts. They are also introduced to the concepts of relative minima and maxima and determining the possible degree of the polynomial by noting the number of relative extrema by looking at the graph of a function.
