Answer: The required point is (-4, 7).

Step-by-step explanation: Given that the point (7, -4) lies on the graph of the function
f(x).

We are given to find a point that must lie on the graph of the inverse function
f^(-1)(x).

We know that

If a point (a, b) lies on the graph of a function
g(x), then the point (b, a) must lie on the graph of the function
g^(-1)(x).

So, from the given information, we get

the point (-4, 7) must lie on the graph of the inverse function
f^(-1)(x).

Thus, the required point is (-4, 7).

If (7, -4) is on the graph of F(x), then (-4, 7) is on the graph of F⁻¹(x).
