Question

The graph of f(x) is show below.

If f(x) and it’s inverse function f^-1(x) are both plotted on the same coordinate plane where is their point of intersection?

Answer 1

Did the test. Answer is (2,2).

Answer 2

(2,2)

Step-by-step explanation

Since f(x) and its inverse function are symmetric about the line y=x, if (a,b) lies on the graph of f, then (b,a) must lie on f inverse.

The point (2,2) lies on f and the same time on f inverse.

The solution is a point that satisfies both equations.

Hence the correct choice is:

(2,2)
