Question

look at this set of ordered pairs: (3, 17) (3, 18) (2, -5) (2, 10) (3, 12) 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

For the x - value 3, we have y - values 17, 18, 12. For the x - value 2, we have y - values - 5, 10. Since x = 3 and x = 2 have multiple y - values, the relation is not a function.

Answer:

no
