I need answer for this please

The function f(x) = x +5 is one-to-one. a. Find an equation for f (x), the inverse function. b. Verify that your equation is correct by showing that f (f (x)) = x and f (f(x)) =x. a. Select the correct choice below and fill in the answer box(es) to complete your choice. (Simplify your answer. Use integers or fractions for any numbers in the expression.) O A. f ( x) = , for xs O B. f (x) = , for all x O c. f ( x ) = . for x2 OD. f (x) = , for x # b. Verify that the equation is correct. f ( f 1 (x)) = ( ]) and F 1 (F( x ) = F' (0) Substitute. = Simplify. The equation is
