Answer:

  (4, -2)

Step-by-step explanation:

If (x, y) is part of the relation f, then (y, x) will be in the inverse relation f^-1.

The point contained in f^-1(x) is (4, -2).

_____

<em>Additional comment</em>

The range of f is {2, -4, -2, -4}, which has -4 repeated. That means <em>the inverse relation is not a function</em>. We can say that (4, -2) is a point contained in the inverse relation, but we cannot say that f^-1(x) is a function.
