Relations and Functions

Overview

This chapter begins with introductions to the coordinate plane, relations, and functions. Function rules are discussed. Linear functions are then introduced, along with their graphs, slopes, and y-intercepts. Translations are discussed at the end of the chapter.

What you can expect to learn

After completing these activities you should be able to

  1. Identify the quadrant or axis on which a point is located.
  2. Answer basic questions about relations and functions.
  3. Determine whether a given ordered pair satisfies a given function rule, and be able to find function values.
  4. Find ordered pairs based on a linear function.
  5. Determine the slope of a line from the coordinates of two points on the line.
  6. Use translations to change the position of a point.
