Answer:
The Relation is a function
Step-by-step explanation:
Our x terms are -5 7 3 and 1. They do not repeat with a different answer. example: if there is (1,2) and (1,3) then it is not a function because there is 2 possible outcomes 2 and 3 meaning it would fail the vertical line test. So in this case the relation is a function. Hope this helped!
