First I isolate the ln( ) function: Now to eliminate the ln( ) part, I raise both sides as exponents of e: This makes the e and the ln cancel each other on the left side, dropping the 5t + 1 down: and I continue to isolate t in the usual way: Not a very pretty answer, but that is the inverse of f(t). Now you try yours.
