Question

Identify the domain and range of the relation. {(-9,2), (-4, 2), (3, 2), (9,2)​

Answer 1

Domain: - 9, - 4, 3, 9

Range: 2

Explanation:

The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. The range is the second coordinate of an ordered pair. This means that the range is going to be y. Since all of the second coordinates are 2 you only have to put 2 once. The domain of the set of ordered pairs is - 9, - 4, 3, 9.
