F(X)满足F(x)+2f(x分之1)=3X,求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)+3f(x分之1)=4x,求f(x) 若f(x)满足f(x)-2f(1/x)=x,则f(x)=? 若F(x)满足f(x)+2f(1/x)=x,则f(x)= f(x)满足:2f(x)-f(1/x)=x+1,求f(x) 设函数f(x)满足f(x)+2f(1/x)=x,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) 已知f(x)满足f(x)+2f(1/x)=3x,求f(x) , 若一次函数f(x) 满足f[f（x)]=1+2x 求f(x) f(x)满足f(-x)+2f(x)=x+3,则f(1)等于 为什么f(x)满足f(x+1)=1/f(x)可以得出f(x+2)=f(x） 二次函数f(x)满足f(x+1)+f(x-1)=2x^2+4x,求f(x) 若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)= 已知函数f(x)满足2f(x/1)-f(x)=x ,x不等于0,则f(x)等于 函数f(x)满足f(x)-2f(1/x)=x+x三次,求f(x)的解析式 设f(x)满足f(x)+f'(x)+f(x)=e^x+2,且f(0)=1,f'(0)=0,求f(x)
