Representing Polynomials

Use this complete and very detailed lesson plan to assess your students' understanding of two important behaviors of polynomials. The first is the relationship between the zeros of a polynomial function and the function's graph, and the second is how to recognize the effect on the graph when f(x) is replaced by f(x) + k, f(x + k), -f(x), and f(-x). The instructional activity includes follow-up activities and exercises to strengthen weak areas highlighted by the initial assessment.
