f(x-1)=x^2-2x+3(x

F(X)满足F(x)+2f(x分之1)=3X,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x)? 已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x) f(x)=x(x-1)(x-2)(x-3)(x-4) f'(1)=? f(x-1)=x^2-2x+3(x f(x)=(x-1)(x-2).(x-3)求导 已知f(x+1)+2f(-x)=3x²+x,求f(x) F(x)=3x^2+2x-1 求F(x+△x)-f(x)/ △x f(x)=x/(x^2+1) 1.f(x)=1-x² 2.f(x)=-3x+1 3.f(x)=2/x 4.f(x)=(x-x²)/ 求f(x)=(x-2)^2/(x+1),f(x)=(x^2+9)(x-3/x)的导数.
