K a. Find the inverse of the function below on the given interval and write it in the form y=f^(x). b. Verify the relationships f(f(x)) =x and f(f(x)) = x. f(x)=(x-6) 5 A. 9 5 9 f(f(x)) = X +6-6 =X B. (1) = (x-6)) =X (Type integers or simplified fractions.) Verify the relationship f1 (f(x)) = x. Select the correct choice below and fill in the answer box(es) to complete your choice. OA. 5 9 f(f(x)) = (-6)=x OB. f(f(x)) = ((x-6) ((x-69)) 5 =X lified fractions.)
