In Lesson 6.1, you learned about the many ways in which relations can be represented. The following example looks at three different relations, with different representations, and their domains and ranges.

Example 2

For each of the following relations,

  • State the type of representation.

  • State the domain and range in list form.

 

When stating a domain or range in list form, as shown in Example 2, the numerical values are listed in ascending order. As such, the first domain value and the first range value do not necessarily represent an ordered pair of the relation.

 

Example 3

Determine the domain and range of the relation represented in the graph below using number lines and algebraic notation.
