The function f(x) = 5x + 7 is one-to-one. a. Find an equation for f1, 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.) OA. f(x)= for all x OB. f(x) = O c. f(x) = for x # OD. f(x)=, for x b. Verify that the equation is correct. f(f(x)) = f( = for x s The equation is and f (f(x)) = f) = Substitute. Simplify.
