Relations and Functions

In earlier math courses, you have seen relations and functions represented by tables, sets of ordered pairs, and graphs. In this topic, you will continue to explore these representations, and you will be introduced to mappings to represent relations and functions. You will also learn how function notation is used to represent functions, and investigate characteristics of the linear and quadratic function families.

Essential Questions

  • How can you determine if a relation is a function?
  • How can you represent a relation in multiple forms?
  • How can you determine the domain and range of a function?
