f(x)= 2^x (x≥2)f(x+2) (x＜2)则f(log4 5)为？

f(X)=f(X+2)(x f(x)=x^2+x (x f(x+2)>=f(x)+2,f(x+3) f(x)是奇函数,x≥0时,f(x)=x+x^2,求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)= 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) f(x)满足:2f(x)-f(1/x)=x+1,求f(x) 已知f(x)满足f(x)+2f(1/x)=3x,求f(x) , x-2 ,X>=0 f(x)=f[f(x+5)],x分段函数f(x)= x-2 ,X>=0 f[f(x+5)],x f(x)+f((x-1)/x)=2x; x!=0,1; 求f(x) f(x)+f[(x-1)/x]=2x x不等于0,1.求f(x). max{f(x),g(x)}=1/2(f(x)+g(x)+|f(x)-g(x)| 已知f(x)=x^-2(x
