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

(3,3)

Explanation:

Answer 2

Recall that the inverse function is the same function reflected over the line y=x. So the only points that will remain the same (and thus intersect) will be ones where the point already follows the relationship y=x. In this case, the only point that fits this description is (3,3).
