设函数f1(x)=x^1/2,f2(x)=x^-1,f3(x)=x^2,则f3(f2(f1(2007)))=?
设函数f1(x)=x^1/2,f2(x)=x^-1,f3(x)=x^2,则f1{f2[f3(2007)]}=
f1(x)=x^2,f2=(x^-1),f3(x)=x^3,则f1(f2(f3(2007)))=?
设函数f1(x)=x1/2 f2(x)=x-1 f3(x)=x2 (注:x后的是指数),则f1(f2(f3(2012))
已知函数f1(x)=x,f2(x)=(1/2)^x-1,f3(x)=a-x,函数g(x)取f1(x),f2(x),f3(
设函数f1(x)=x12,f2(x)=x-1,f3(x)=x2,则f3{f2[f1(2011)]}=( )
已知函数fx=x^2/(1+x^2),那么f1+f2+f1/2+f3+f1/3+f4+f1/4
对于函数f(x)=(x-1)/(x+1),设f1(x)=f(x),f2(x)=f[f1(x)],f3(x)=f[f2(x
设函数f1(x)=x的1/2次方,f2(x)=x的-1次方,f3(x)=x的平方,
设f(x)=|1-2x|,x∈[0,1],记f1(x)=f(x),f2(x)=f[f1(x)],f3(x)=f(f2(x
设函数f(x)是f1(x)=4x+1,f2(x)=x+2,f3(x)=-2x+4三个函数的最小值,则f(x)的最大值为
