A tanning salon charges a one time maintenance fee of $12 plus $4 for each tanning visit. Write a function to describe the situation. Find a reasonable domain and range for the function for up to 6 visits.

Answer: f (y) = 12 + 4x

Range = $24, Domain = {16,20,24,28,32,36}

Step-by-step explanation:

f (y) = 12 + 4x where x is the number of visits.

f (1) = 12+4 = $16

f (6) = 12+4 (6) = 12+24=$36

The range = f (6) - f (1) = 36-12 = $24

the domain = all possible values of x so it is {16,20,24,28,32,36}

The answer is f (y) = 12 + 4x
