I need help with this as soon as possible please and thank you?!!! ??

The function f(x) = 3x + 2 is one-to-one. a. Find an equation for F1 , the inverse function. b. Verify that your equation is correct by showing that r(t' 1 (x)) = x and r" 1(too) = x. W@ a. Select the correct choice below and ll in the answer box(es) to complete your choice. (Simplify your answer. Use integers or fractions for any numbers in the expression.) 0 A. f1(x)=j.forx[:] O B. f_1(x)=w,forx2|::] o D. f"1(x)=,torxs b. Verify that the equation is correct. t(f\"(x)) = (D) and r'1(r(x)) = f\"1 (D) Substitute. D = D Simplify. The equation is
