Absolute Extrema of Function

Let x = –1 and x = 2 be the critical points of the function f(x) = x³ + ax² + b log_e|x| + 1, x ≠ 0. Let m and M respectively be the absolute minimum and the absolute maximum values of f in the interval $\left[ { - 2, - \frac{1}{2}} \right]$ . Then |M + m| is equal to - (Take log_e2 = 0.7) :
