Does the relation describe a function? Explainyour reasoning.

Domain Range

-2 5

-1 6

0 7

1 8

2

(arrow from - 2 to 5, from - 1 to 8, from 0 to 6, from 1 to 6, and from 2 to 7)

Yes because the numbers don't repeat.

Yes, it is a function.

Each element in the set called the domain is related to exactly one output in a set called the range.

A function can have several inputs that provide the same output, but a function should never have one input that results in multiple outputs.
