If `f(x) = (1-x)/(1+x)` then find the value of `f{f(1/a)}`

If f(x) = (x + 1)/(x-1) , then the value of f{f(3)} is :

If f(x)=x^(3)-(1)/(x^(3)) , then find the value of f(x)+f(-x) .

If f(x) = x - (1)/(x) , then the value of f(x) + f((1)/(x)) is :

If f(x)=(x+1)/(x-1) then the value of f(f(f(x))) is :

If f(x) = x/(x-1)=1/y then the value of f(y) is

If f(x)=1-1/x then write the value of f(f(1/x))dot

If f'(x) = 1/x + x^2 and f(1)=4/3 then find the value of f(x)

Ilf f(x)={x^3, x 2 , then find the value of f(-1)+f(1)+f(3) . Also find the value (s) of x for which f(x)=2.

Let f : W-> W be a given function satisfying f(x) = f(x-1)+f(x-2) for x<=2 .If f(0)=0 and f(1)=1 , ther find the value of f(2) + f(3) + f(4) + f(5) + f(6) .

If a continuous function f on [0,a] satisfies f(x)f(a-x)=1,agt0 , then find the value of int_(0)^(a)(dx)/(1+f(x)) .
