Keith used the following steps to find the inverse of f, but he thinks he made an error. Step 1 given
Step 2 change f(x) to y
Step 3 switch x and y
Step 4 add 5 to each side
Step 5 divide each side by 7
Step 6 change y to g(x)
Step 7 switch sides of the equation

C.
Keith did not make any errors.
D.
