Question

If f(x) and its inverse function, f–1(x),

are both plotted on the same coordinate plane, what is their point of intersection?

a)
(0, –2)
b)
(1, –1)
c)
(2, 0)
d)
(3, 3)

Answer 1

answer is d

Explanation:

Answer 2

Option d) (3,3)

Explanation:

A function f(x) and its inverse f^(-1) (x) are symmetrical with respect the right line y=x, then their point of intersection is when they cross the right line y=x. In the attached graph we draw the right line y=x, and the function f(x) crooses this line at the point (3,3), then this point is their intersection point.
