The graph of F (x) can be flipped over a certain line to produce the graph of its inverse. What is the equation of that line?

A. y = - x

B. y = x

C. x = 0

D. y = 0

The correct answer is:

y=x.

Explanation:

In order to find the inverse of a function, we first switch x and y; then we isolate y. When we do this, we are saying that x and y equal the same thing, or y=x.
