A2 Verifying Inverses with Compositions Practice

What are you supposed to do Algebraically to verify that the two functions f(x) & g(x) are inverses of each other?

• Verify the f(g(x)) = x only

• Verify that g(f(x)) = x only

• Verify that BOTH f(g(x)) = x & g(f(x)) = x

• Inverse Functions
• Not Inverse Functions

To graph the inverse of a function...

• Rotate it around the origin

• Reflect it across the x-axis

• Reflect it across the y-axis

• Switch the x and y coordinates and plot the new points
