Question

look at this set of ordered pairs: (8, -11) (9, 15) (15, -9) is this relation a function? yes no submit

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

The ordered pairs are \((8, - 11)\), \((9,15)\), \((15, - 9)\). The x - values are 8, 9, and 15. Each x - value appears only once, so each input has exactly one output.

Answer:

yes
