1. The problem statement, all variables and given/known data
Suppose that f has an inverse and f (6) = 18, f'(6) = 4/5. If g = 1/(f-1), what is g'(18)?

have no idea how to set up problem

Do you read your textbook at all? If not then you should! In it you'll find a theorem that specifically deals with derivatives of inverse functions. Please flip through the section in which this exercise occurs and see if you can't find it. Then we can get started.
