Thread: Inverse f(x)

Well. I have to figure out the inverse function of a particular function.

That function being ln|x-2| + 3.

I got it to x-3 = ln|y-2|, but how do I get y on it's own? I imagine it has some to do with e^x considering it's ln|x|'s inverse.

Well I think I've got it now to be e^(x-3) + 2

Are you sure you not given an interval in the question?
This function is not one-to-one function.

That's only half of the truth ...

1. I assume that the function is



2. Each "branch" of f is a one-to-one function. Therefore you have to calculate 2 different inverses.
