Question

How do you find the domain and the range of the relation (7 ,4),(-1,- 4),( 2, 4))?

Answer 1

The domain is the set of x-values, and the range is the set of y-values.

Explanation:

Your domain contains each of the first numbers from each ordered pair: `{7, -1,2}` and your range is `{4, -4 }` without having to repeat the value 4.
