" If "f(x)=(x-1)/(x+1),x!=+-1," then verify "fof^(-1)(x)=x

If f(x) = (x-1)/(x+1), x ne -1, 1 , then "fof"^(-1) is

If f(x)=(3x-1)/(x+1),xne-1 , then find fof (x).

If f(x)=(x-1)/(x+1),x ne pm1, show that fof^(-1)(x)=x .

If f(x) = (3x - 1)/(x+1), x ne (-1) then find fof (x).

If f(x)=x/(x-1) , x!=1 Find fof(x)

If f(x) = frac{3x-1}{x+1} , x != -1 then find fof(x).

If f(x)=(x)/(x-1),xne1 , then show that fof (x) = x.

If f(x)=(x)/(1-x);x!=1 then f^(100)(x) is [where (fof (x)=f^(2)(x)]

Is f(x) = (x-1)/(x+1) invertible in its domain ? If so find, f^(-1) Further verify that (fof^(-1))(x) =x.
