If 
is the inverse of 
, then
Given
composing with the inverse function gives
Solve for the inverse:
Answer:
B is the answer
Step-by-step explanation:
The equation representing the given relationship is
y = 0.50x + 15
Given, The cost for renting a car a day is $0.50 per mile, plus a $15 flat fee.
we have to find an equation to represent the given relationship.
Let the number of miles driven be, x
and the total cost be, y
total cost = cost per mile × miles driven + flat fee
Total cost = 0.50 × miles driven + 15
y = 0.50x + 15
Hence, the equation representing the given relationship is
y = 0.50x + 15
