Find the difference quotient f(x) - f(2) when f(x) = 4- 3x - 4x2. Simplify the expression fully as if you were going to x - 2 compute the limit as x - 2. In particular, cancel common factors of x - 2 in the numerator and denominator if possible. (Use symbolic notation and fractions where needed.) f(x) - f(2) x - 2 Use your result to compute the derivative. (Give your answer as a whole or exact number.) f'(2) =
