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. Keith did not make any errors. C. In step 5, Keith should have multiplied each side of the equation by 7. D. In step 4, Keith should have subtracted 5 from each side.
