Question

If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is their point of intersection?
(0, 6)
(1, 4)
(2, 2)
(3, 0)

Answer 1

The graphs of a function and its inverse are mirror images across the line y = x, so their intersections must lie on y = x (points where f(x) = x). The only choice with x = y is (2, 2).
