A relation is a pairing of x and y values. Domain can be defined as all of the x-values in a given relation. Range can be defined as all of the y-values of a relation.

Consider the relation given by the set of ordered pairs: (-2, -3), (-1, 1), (1, 3), (2, -2), (3, 1). When you list the domain and range, the numbers need to be listed from least to greatest. The domain of the relation is {-2, -1, 1, 2, 3}. The range of the relation is {-3, -2, 1, 3}. When you have an x or y value that appears more than once, you only need to list the value once. Here is a list of other commonly used terms that can be used in place of domain and range: Domain: x-value, input, independent variable Range: y-value, output, dependent variable A relation can be represented in multiple ways. Five ways to represent relations are using ordered pairs, tables, graphs, rules, and in contextual situations. Example: Given the following contextual situation, write the relation using each of the representations.

Co ntext: You are thinking about treating 5 of your friends to some ice cream sandwiches down at the Snack Shack. Each ice cream sandwich costs $2.00.

The number of friends represents the independent variable. The total cost represents the dependent variable. Table
