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.

After completing these activities you should be able to

  1. Describe relations and functions by using multiple representations.
  2. Write function rules describing the relationship between 2 variables.
  3. Solve real-world problems using function rules and graphs.
