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 a. in step 6, keith should have switched x and y. b. in step 4, keith should have subtracted 5 from each side. c. in step 5, keith should have multiplied each side of the equation by 7. d. keith did not make any errors.
