Answer: They are inverses of each other
============================================================
Explanation:
We need to check two things:
- f(g(x)) = x
- g(f(x)) = x
If both of those equations are true, then f and g are inverses of each other.

Part 1
So far, so good. Now we need to check the other equation mentioned.
------------------
Part 2
That works out as well. Both equations mentioned are true, which confirms the two original functions are inverses of one another.
