Step-by-step explanation:

The domain of a relation are the input values. In this image the domain is represented by the begining of the arrows (the values on the x column).

The range are the output values. In this case they are the ends of the arrows (the values on the y column)

Answers:

• Domain: {5, 10, 15, 20}

,

• Range: {-3, -1, 1, 3}

,

• Description: ,this is an injective function, because it is a one to one relation
