Question

look at this set of ordered pairs: (8, -9) (6, 17) (14, 9) (-2, 8) (0, 10) is this relation a function? yes no

Explanation:

Step1: Recall function definition

A relation is a function if each input (x - value) has exactly one output (y - value).

Step2: Check x - values

List the x - values of the ordered pairs: 8, 6, 14, - 2, 0.
Each x - value appears only once. So each input has exactly one output.

Answer:

yes
