若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?f(x)+2f(1/
若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?
若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?
若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?
f(x)+2f(1/x)=3x,(1)
令x=1/x,则有
f(1/x)+2f(x)=3/x,(2)
将f(x),f(1/x)当作两个未知数解出f(x),
由(1)-(2)*2
得到:
-3f(x)=3x-6/x
所以
f(x)=-x+2/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)=
若一次函数f(x) 满足f[f（x)]=1+2x 求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)
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(-x)=-3x+1,求f(x)
已知f(x)满足f(x)+2f(1/x)=3x,求f(x) ,
若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)=
若一次函数f(x)满足f[f(x)]=1+4x,求f(x)
f(x)满足f(-x)+2f(x)=x+3,则f(1)等于
若f(x)满足3f(x-1)+2f(1-x)=2x,则f(x)=?
若函数f(x)满足关系式f(x) 2f(1/x)=3x,则f(x)=
若f(x)满足f(x)+2f(1/x)=3x,则f（x）=?
