If `f(x)=(1-x)/(1+x),` then `f((1-x)/(1+x))` is equal to

If f(x)=(1-x)/(1+x) then f{f((1)/(x))}

f(x)=(1-x)/(1+x) then f{f((1)/(x))}

If two roots of the equation (p-1)(x^(2)+x+1)^(2)-(p+1)(x^(4)+x^(2)+1)=0 are real and distinct and f(x)=(1-x)/(1+x) then f(f(x))+f(f((1)/(x))) is equal to

If f(x) = log_(e) ((1-x)/(1+x)) , then f((2x)/(1 + x^(2))) is equal to :

If f (x) = (x-1)/( x+1) , then f ((1)/( f (x))) equals

If f(x) = log ((1+x)/(1-x)) , then f((2x)/(1+x^(2))) is equal to

If f(x)=x^(3)+(1)/(x^(3)), then f(x)+f((1)/(x)) is equal to

If f(x)=log_(e)((1-x)/(1+x)),|x|<1, then f((2x)/(1+x^(2))) is equal to:

If f(x)=(1)/(1-x), then f(f(f(x))) is equal to

If f(x)=log((1+x)/(1-x)) , "then f "((2x)/(1+x^(2))) is equal to
