If `f(x)=1-1/x`, then `f(f(1/x))` is
`(A) 1/x`
`(B) 1/(1+x)`
`(C) x/(x-1)`
`(D) 1/(x-1)`

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

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

if f(x)=1/(1-x) then find f((x-1)/x)

If f(x)=(x-1)/(x+1) then f^(-1)(x)=?

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

If f(x)=(x-1)/(x+1), then f(f(ax)) in terms of f(x) is equal to (a) (f(x)-1)/(a(f(x)-1)) (b) (f(x)+1)/(a(f(x)-1))(c)(f(x)-1)/(a(f(x)+1))(d)(f(x)+1)/(a(f(x)+1))

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