Find the derivative of the function by using the product rule. Then multiply out the function and nd the derivative by treating the function as a polynomial. Compare the results. y=(x-1)(4-3x) Which of the following shows the result of using the product rule to nd the derivative of the given function? d d -"A. (x- 1)a(4-3x)+ (4-3x)dx(x- 1) d d B. (X'1)a(x-1)+(4-3x)a(4- 3x) (4 3x)%(x 1)(x 1)%(4 3x) (x 1)2 (4 3x)i(4 - 3x) (x -1)i(x 1) dx dx (x 1)2 The derivative using the product rule is y' = 7 6x . Multiplying the function out results in the polynomial D. (Simplify your answer. Do not factor.)
