I just need the 4 empty boxes on question (B) please. Try to keep it simple.

6x + 1 The function f(x)= is one-to-one X - 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 choic (Simplify your answers. Use integers or fractions for any numbers in the expression.) O A. f (x) = , for all x B. f (x) = 7x +1 x-6 . for x 6 O c. f (x) = . for x2 OD. f (x) = , forxs b. Verify that the equation is correct. (Simplify your answers. Use integers or fractions for any numbers in the expression.) i(f ' (x )) = 1(D and ( f ( x ) = f - 1 Substitute x Simplify
