What is the DOMAIN of this relation? Write your answer.

Domain = {-4, -1, 0, 2, 7, 8, 13}

The domain is the set of allowed x inputs. So all we do is list the set of x values in the top row of the table.

In contrast, the range is the set of possible y outputs. So the range would be {5,2,-3,7,4,9}. Any duplicate items in the range are tossed out. Optionally you can order the set from smallest to largest, but that's not required. This is because order in a set doesn't matter.

4 + 5 7/9= 9 7/9
