Remember, you've got two ways you can double-check this answer to see if it's right:
|Graph||and||on the same graph and|
|see if they're mirror images over the line y = x.|
(Easy -- since these are both lines.)
|(or both for practice!)|
*Note: This is just like ( f o g )( x ), but with different notation.
OK, here's the list of steps:
|How to find the inverse of a function:|
STEP 1: Stick a "y" in for the "f(x)."
STEP 2: Switch the x and y.
STEP 3: Solve for y.
THEN, CHECK IT!
