Answer:
(4, -2)
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).
_____
Additional comment
The range of f is {2, -4, -2, -4}, which has -4 repeated. That means the inverse relation is not a function. 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.
