Option B) domain: 3, 10, 15 range: 7, 18, 21

Step-by-step explanation:

we have

{ (3, 7), (10, 18), (15, 21) }

Remember that

The domain are all possible values of x or input values of the function

The range are all possible values of y or output values of the function

In this problem

the input values are 3,10,15

the output values are 7,18,21

therefore

domain: 3, 10, 15 range: 7, 18, 21
