Inverses
Finding Inverses
Recall from earlier lessons, that inverse graphs are reflections across the line y = x. To find the inverse of a power function, switch the x and y and solve for y. To graph the inverse of a power function, switch the x and y-coordinates of the points and plot the results.
Example Find the inverse of the function: y = x2 , then graph both equations.
Step 1. Switch the x and the y.
x = y2
Step 2. Solve for y.
The inverse of 
is 
Step 3. Graph the equations.
