I also need to know what the derivative is

Differentiate the function. f(x) = (8x2 -2x+9) (4x2+3x-5) Which of the following shows how to find the derivative of f(x)? (8x2 - 2x + 9) d dx (4x2+ 3x-5) dx (8x2- 2x + 9) (4x2 + 3x -5) O A. f' ( X ) = (8x2 - 2x+ 9) 2 d dy (8x2 - 2x + 9) (4x2+ 3x-5) - (8x2 - 2x+9) d (4x2 + 3x -5) O B. F' ( X ) = dx (4X2+ 3x-5)? O c. f'(x ) = dy (8x - 2x + 9) (8x2 - 2x+9) + (4x2+3x-5) dx (4X2+ 3x -5) OD. f' ( x) = (8x2 - 2x + 9) (4x2 + 3x - 5) + (8x2 - 2X + 9) (4x2 + 3x - 5)
