Functions

Overview

This chapter reviews the representation of relations and functions using mapping diagrams, graphs, and function rules. Students will use graphs and equations to model real-world applications of functions, including direct and inverse variations and arithmetic sequences. The chapter concludes with graphing absolute value functions.
