f(x) gives the cost (in thousands of dollars) of buying x acres of land in a remote area of Vermont. Carefully interpret the following:
a) f(50) (your answer should take the form "f(50) is...")
b) f^-1 (50) (your answer should take the form "f^-1 (50) is....")

I am good at math and I will not answer the question.
However, I admit that the title was catchy and caused me to look. And for that, I will give you a hint.
a) is easy as it is simply a rewrite of the general statement, with a value for x.
b) took me a few seconds. It is easier if you think of it in terms of g(y), where g is the inverse function to f (what the question calls f^-1) and y is the variable that takes on the value 50.
ff gives me the cost of buying acres
g(y) gives me the number of acres I can buy with...

a) f(50) is the cost (in thousands of dollars) of buying 50 acres of land in a remote area of Vermont.
b) f^-1(50) is the number of acres of land in a remote area of Vermont which can be purchased for 50 thousand dollars.
That wasn't so bad, was it? ☺

Well, I got an A in Math 12, Calculus and Algebra and I'm trying to figure what the point of your question is...
This isn't even close to a "real" math problem for anyone that truly understands math. Sorry.

Nice try, but challenging my ego is not going to trick me into doing your math homework for you.
