f(x)=2x/x+2 f(x)+f(m-x)=4 x大于-2恒成立,求M

f(X)=f(X+2)(x f(x+2)>=f(x)+2,f(x+3) f(x+4)=-f(x) 奇函数 [0,2]增 f(x)=m m f(x)=x^2+(m+1)x+m+n+1 f(0)>0 f(1) f(x)=x^2+x (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) , 已知f(x)=(m+1)x^2-(m+1)x+1,写出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 设f（x)满足f(-x)=-f(x),f(x)=f(4-x),x∈[0,2)时,f(x)=x,则f(11.5)等于? f(x)+f((x-1)/x)=2x; x!=0,1; 求f(x)
