If f(x) and its inverse function, fx), are both plotted on the same coordinate plane, what is their point of intersection?
Lubov Fominskaja [6]

Answer: (3, 3)

Step-by-step explanation:

the graphs of f and f^{-1 are flipped: if the point (x, y) is on the graph of f, then the point (y, x) is on the graph of f^{-1.

Any points of intersection will satisfy (x, y) = (y, x). A point that satisfies this property must have the same x and y coordinate. (Think about it.) The only point on f like that is (3, 3), so that is the point of intersection.
