Answer 1

Step-by-step explanation

The domain of a relation is all the x-values it has.

The range of a relation is all the y-values it has.

This relation is expressed as a group of ordered pairs - in ordered pairs the value on the left is the x-value and the one on the right is the y-value.

A relation is a function if and only if for each x-value there's only one y-value. For one y-value it can be one or two different x-values.

Answer

• Domain: {-3, 0, 1, 2}

,

• Range: {-6, 0, 2, 4}

,

• This relation ,is, a function, because there are not repeated x-values.
