2. Re: c3 help solomon
I'm guessing that if f(x) = 1+ (x-4)^0.5
then your transformation would have been correct.

But because it is the INVERSE of f(x), then the transformation is the opposite (inverse) way around.
so you ups become down and your rights become left...

like i said, i'm guessing though (trying to bump your post up so others can help )
