Final answer:
The domain of the given relation, which includes the ordered pairs (9, -2), (4, 3), (8, 10), and (-4, 8), is the set {9, 4, 8, -4}.
Step-by-step explanation:
Domain of a Relation
The domain of a relation is the set of all the first elements from each ordered pair in the relation. In the case of the given relation with the ordered pairs (9, -2), (4, 3), (8, 10), and (-4, 8), the domain consists of the first values from each pair. To list the domain in set notation, we collect these first elements: {9, 4, 8, -4}. Therefore, the domain of the given relation is {9, 4, 8, -4}.
