Given the function f (x) = x ^ 2 + | X-1 |, G (x) = x ^ 3-ax (a)

Very simple, the maximum value on the left is 3, the maximum value on the left is less than or equal to the maximum value on the right, and then discuss the maximum value on the right, the maximum value calculated by derivation (pay attention to the range of values) and G (2), G (3) three cases
