Question

Please help me answer question 2 on my algebra 1 homework

Answer 1

c = 34.95u + 6.25

The domain of the function is the set of possible values of u, wich is [8, 12]

The range is the set of the possible values of c.

Since 34.95*8 + 6.25 = $285.85 and 34.95*12 + 6.25 = $425.65, the range is [285.25, 425.65]
