Final answer:
The set of numbers that makes up the domain in the given relation is -2, 0, 2, and 3.
Step-by-step explanation:
The domain of a relation is the set of all the x-values (or inputs) in the relation. In this case, the x-values are -2, 0, 2, and 3, which are the first values in each ordered pair in the relation.
So, the set of numbers that makes up the domain in the given relation is: -2, 0, 2, and 3.
