The cost of producing q articles is given by the function C=f(q)=100+2q.
(A) Find the formula for the inverse function.
(B) Explain in practical terms what the inverse function tells you.
I am pretty sure the answer to A is f^1(C)=C/250
For B, the inverse of the function is the interchange of the dependent and indepent variable.

C = 100 + 2q
q = (100C)/2 = 50  C/2
The inverse function is
f^1 (C) = 50  (C/2)
f^1 is the function that gives you the number of items you can produce when you input the price, C
