Given the function f (x) = X21 + X2, then f (12013) + F (12012) + F (12011) + +f(12)+f(1)+f（2）+f（3）+… +f= ___ ．
∵ f (x) = X21 + X2, ∵ f (LX) = (LX) 21 + (LX) 2 = 11 + X2, from which we can get f (x) + F (LX) = X21 + x2 + 11 + x2 = x2 + 11 + x2 = 1. ∵ f (12013) + F (12012) + F (12011) + +f(12)+f(1)+f（2）+f（3）+… +f=[f(12013)+f(2013)]+[f(12012)+f(2012)]+… +{f(12)+f...
