Question

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)

Answer 1

Yes because the numbers don’t repeat .

Answer 2

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.
