f(x)=1.5x-3.5 f(2x+1)=?f(x)=1.5x-3.5 f(2x+1)=?耍七天忘了这是怎么做的了

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) 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) , 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)| f(X)=f(X+2)(x f(x+2)=1/f(x),f(1)=5;问f(f(x))? f(x+2)=1/f(x),f(1)=-5,f[f(x)]等于多少? f(x)={2x+1,x f(x)={1+x/2,x f(x)=(x-1)/(x+2)
