If `x ne 1 and f (x) =(x+1)/(x-1)` is a real function, then `f (f(f(2)))` is

If x ne 1 and f (x) = (x +1 )/( x-1) is a real function then fff (2) is

If f (x) = (x + 1)/(x - 1) is a real function , x ne 1 , then f [f(2)] is . . . .

If f(x)=x^(2) is a real function, find the value of f(1).

If f(x)=x^(2) is a real function, find the value of f(1).

If f is a real function, find the domain of f(x)=(1)/(log|x|)

If f(x)=(1)/(x)-1 where x ne 0, then: f(x)-2.f(2x)=

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

If f(x)=(1)/(x)-1 where x ne 0, then: f(x)+f(-x)+2=

If f(x)=(x+1)/(x-1), x ne 1 , find f(f(f(f(f(2)))))

If f(X) = (x^2-1)/(x-1 for x ne 1 and f(x) = 2 when x = 1. Show that the function f(X) is continuous at x = 1.
