Representing Polynomials Graphically

This lesson unit is intended to help you assess how well students are able to translate between graphs and algebraic representations of polynomials. In particular, this unit aims to help you identify and assist students who have difficulties:

• Recognizing the connection between the zeros of polynomials when suitable factorizations are available and graphs of the functions are defined by polynomials.
• Recognizing the connection between transformations of the graphs and transformations of the functions obtained by replacing f(x) by f(x + k), f(x) + k, -f(x), f(-x)..
