Let h(x) = 14), where f(x) = –2x – 3 and g(x) = x2 – x + 2. What is h' (x)? Select the correct answer below: 2x2 +6x–7 *4–2x3 +5x2–4x+4 -6x2–2x-1 x+-2x3 +5x2-4x+4 2x2+6x–7 x-x+2 O za
(1 point) Let f(x) = 3x - 2x + 9. Then according to the definition of derivative f'(x) = lim (Your answer above and the next few answers below will involve the variables x and h. We are using h instead of Ax because it is easier to type) We can cancel the common factor from the numerator and denominator leaving the polynomial Taking the limit of this expression gives us f'(x) = -4x+3
