How do you solve the four-step process?

Use the four-step process to find f'(x) and then find f'(0), f'(5), and f'(6). f(x) = 2x~ + 3x - 2 f' (xx) = f' (0) = (Type an integer or a simplified fraction.) f' (5) = (Type an integer or a simplified fraction.) f'(6) = (Type an integer or a simplified fraction.)
