Ask the college entrance examination questions, what is the solution of 20 14 Zhejiang science mathematics finale 22 questions? This problem is too troublesome to calculate. As we all know, the function f(x)= 1 This topic examines the comprehensive application of derivatives, the maximum value of functions, classification discussion, reduction and transformation. It is difficult, the process is not necessarily particularly complicated, but the thinking should be clear. The answer is here/exercise/math /8044 14. Then don't forget to take my answer, dear.

The function f (x) = x 3+3 | x-a | is known. A belongs to R.

{1} If the maximum and minimum values of $f(x)$ on [- 1, 1] are denoted as m (a) and m (a) respectively, find m (a)-m (a);
