What is the correct numerator for the derivative of $f(x) = 3x^2 - x + 4$ AFTER you have combined $f(x + h)$ and $f(x)$ and simplified the result but BEFORE you have factored an 'h' from the numerator. A. $6xh - h + 3h^2 - 2x + 8$ B. $2xh - h + h^2$ C. $6xh - h + 3h^2$ D. $2xh - h + 3h^2$

(a) Find the derivative of f(x)=(x^2+4)(8x−7) by first expanding the polynomials. Enter the fully simplified expression for f(x) after expanding the polynomials. f(x)= f'(x)= (b) Find the derivative of f(x)=(x^2+4)(8x−7) by using the product rule. Let g(x)=x^2+4 and h(x)=8x−7 g'(x)= h'(x)= f'(x)=
