Problem Statement

Two polynomials f(x)=a100x100+a99x99++a1x+a0 f(x)=a_{100}x^{100}+a_{99}x^{99}+\dots+a_{1}x+a_{0} and g(x)=b100x100+b99x99++b1x+b0 g(x)=b_{100}x^{100}+b_{99}x^{99}+\dots+b_{1}x+b_{0} of degree 100 100 differ from each other by a permutation of coefficients. It is known that aibi a_{i}\ne b_{i} for i=0,1,2,,100 i=0, 1, 2, \dots, 100. Is it possible that f(x)g(x) f(x)\geq g(x) for all real x x?
