so what have you done here? note that the domain of the graph would be . why? and it will be in a somewhat similar in shape to ln(x) but it would increase less steeply. why?

do you understand the relationship between a function and its inverse?2) For the graph of the function of f, where x = # of DVDs produced and y = f(x) = Cost of production, what does f^-1(10) represent? (That's f-inverse(10), I wasn't sure if the way I typed it was correct or not.)

say , then we have

now, can you say what was?

yes3) I was given the inverse function of F. Do I get F using the same method I would to get inverse of F only go the other way around?

after you find f, plug in 1and is finding the F function how I should be finding f(1)?
