Answer:

Step-by-step explanation:
In this problem, we have that the cost of renting a car C is a function of the number of days d, and the number of miles driven, m.
There is also a fixed cost F.
So the equation for the cost of renting a car is:

In which a is the daily cost and b is the cost per mile.
A car rental company charges a one-time application fee of 20 dollars, 45 dollars per day, and 15 cents per mile for its cars.
This means that 
Write a formula for the cost, C, of renting a car as a function of the number of days, d, and the number of miles driven, m.

Answer:
f(x) = 
Step-by-step explanation:
h(x) is defined by the formula,
h(x) = -4f(x) + 7
If the graph attached is of the function 'h' and we have to find the function 'f',
h(x) - 7 = -4f(x)
4.f(x) = -h(x) + 7
f(x) = 
Therefore, function 'f' will be defined by,
f(x) =
