Use limits to find the derivative function f' for the given function f. Then evaluate f'(a) for the given values of a.f(x) = 2x3 - 4x; a = -2, 3
A. f'(x) = 6x2-4; f'(-2) = 20, f'(3) = 50
B. f'(x) = 3x2-4x; f'(-2) = 4, f'(3) = 15
C. f'(x) = 3x2-4x; f'(-2) = 20, f'(3) = 15
D. f'(x) = 6x2-4; f'(-2) = -28, f'(3) = 50
