Final answer:
The domain of the relation is {-9, 3, 5} and the range is {5, 4, 73}.
Step-by-step explanation:
The domain of a relation is the set of all the input values or x-coordinates of the ordered pairs in the relation. In this case, the domain is {-9, 3, 5}. These are the x-values of the ordered pairs (-9, 5), (3, 4), and (5, 73).
The range of a relation is the set of all the output values or y-coordinates of the ordered pairs in the relation. In this case, the range is {5, 4, 73}. These are the y-values of the ordered pairs (-9, 5), (3, 4), and (5, 73).
