a. Use the Product Rule to find the derivative of the given function. b. Find the derivative by expanding the product first. f(x) = (x- 5)(4x + 3) a. Use the product rule to find the derivative of the function. Select the correct answer below and fill in the answer box(es) to complete your choice. D SS A. The derivative is (x - 5) ( 4 ) + (4x + 3) ( 1). D O B. The derivative is (x - 5)(4x + 3) ( ). SS O C. The derivative is (x - 5)(4x + 3) + () t 1 O D. The derivative is ( (x -5). Do O E. The derivative is (x(4x + 3). Do b. Expand the product. ted (x - 5)(4x+ 3) = (Simplify your answer.) um t (5 Dow
