Atanning 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.

The function that can be used to describe the situation given will be f(y) = 12 + 4x.

Since the tanning salon charges a one-time maintenance fee of $12 which is the fixed cost plus $4 for each tanning visit. This can be represented by a function which will be:

f(y) = 12 + (4 × x)

f(y) = 12 + 4x

Note that x = number of visits

Therefore f(6) will be represented by:

= 12 + 4x

= 12 + 4(6)

= 12 + 24

= $36

Therefore, the function will be f(y) = 12 + 4x

   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}
