Answer:
Is a relation and a function.
Step-by-step explanation:
Every set of order pairs represent a relation.
Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case
f(-2) = 3
f(2) = 7
f(7) = -12
f(10) = -15
Therefore the relation is a function as well.
