求教：设f(x)满足3f(x)+2f(1/x)=4x,则f(x)= ——.

设函数f(x)满足f(x)+2f(1/x)=x,求f(x) 设函数f(x)满足f(x)+2f(1/x)=2x+1,则f(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) 4、设f(x)满足关系式f(x)+2f(1/x)=3x求函数的解析式 已知f(x)满足2f(x)+f(1/x)=3x,则f(x)= f(x)满足f(x)+2f(1/x)=3x,则f(x)=_______ 设函数f(x)满足f(x+1)-f(x)=2x+3且f(0)=0则f(-2)等于. 设f(x)满足f(x)+2f(1/x)=3x,则f（x）的表达式是_____________ 设f(x)满足f(x)+f(x-1/x)=x求f(x)的解析式
