Which of the following graphs show the correct graphs of the original and inverse.

• 
• 
• 
• 

When two functions are inverses of each other, their graphs reflect over...

• y=x

• x-axis

• y-axis

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

Find the inverse

• f^-1(x) = 2x+16

• f^-1(x) = 2x-16

• f^-1(x) = 2x - 8

• f^-1(x) = x + 16
