point(s) possible Su Use the four-step process to find f' (x) and then find f'( - 2), f'(1), and f' (2). f(x) = 2x + 3x - 2 . . . f' ( x ) = f' ( - 2 ) = (Type an integer or a simplified fraction.) f' ( 1 ) = (Type an integer or a simplified fraction.) f' ( 2 ) = (Type an integer or a simplified fraction.)
