Here is some help with the inverse part.

You likely are starting with

You want to find .
.
SOLVE THAT FOR .

Let me use y instead of all that text...

multiply by
-----the inverse

DOMAIN:
All real numbers except that .
(-infinity,5) U (5,infinity)

RANGE:
You figure this! What happens as x tends toward -infinity or toward infinity?
What happens to near x=5, on either sides?
