#### Answer:

Domain:

Range:

The relation is NOT a function

#### Explanation:

The domain is the set of all x-values (input values)

Domain:

The range is the set of all y-values (output values)

Range:

A function is a relation for which each value from the domain is associated with exactly one value of the range.

So, the relation is NOT a function because the x-value of 10 is associate with y-value of 10 and 9.
