Question

Given the function F(x), you can get a picture of the graph of its inverse F -1(x) by flipping the original graph of F(x) over the line _____.

A.x = -1
B.y = -1
C.y = x

Answer 1

the answer is C. y=x

Answer 2

The inverse of a function is found by switching the x and the y in the equation and solving for the new y. Therefore, when you have a function plotted on an x/y coordinate plane, you can find its inverse by switching the x and y coordinates and plotting the new points. This process makes the function and the inverse be symmetrical about the line y = x. Your choice is C.
