Relations and Functions

Overview

This chapter analyzes relations visually and algebraically, making comparisons and drawing conclusions. After introducing relations and both linear and nonlinear functions, the focus shifts to graphing and writing equations of linear functions. Direct proportions are presented as a special case of linear functions before students are introduced to graphing linear inequalities.
