If f(x)=(1-x)/(1+x), x ne 0, -1 and alpha=f(f(x))+f(f((1)/(x))) , then

If f(x)=(1-x)/(1+x), x ne 0, -1 and alpha=f(f(x))+f(f((1)/(x))) , then

If f(x)=(1-x)/(1+x), prove that f{f((1)/(x))}=1/x[x ne0]

If f(x)=(1-x)/(1+x)" then "f(x)+ f(1/x)=...... where (x)in R-{0,1}.

If f(x)=(x-1)/(x+1),x!=-1, then show that f(f(x))=-(1)/(x) provided that x!=0,1

If f(x)=(x-1)/(x+1),x!=-1, then show that f(f(x))=-(1)/(x), prove that x!=0

If f(x)=(1)/(x)-1 where x ne 0, then: f(x)+(1)/(f(x+1))=

If f(x)=(1-x)/(1+x) ,x>0 then the least value of f(f(x))+f{f(1/x)} is _______
