Best answer

 If the point (a, b) lies on the graph of f(x), then the point (b, a) must lie on the graph of f -1 (x), and vice versa. This means that the graph of f -1 (x) is a reflection of the graph of f(x) in the line y = x.

Therefore, the ordrerd pair of the function is (4, 17).

The option C is correct.
