1.3.If `f(x)=x+(1)/(x)`,then value of `f(x)+f(1/x)` is

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(2)) is

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

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

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

Let f(x) be a function which satisfies f(x^(3))f'(x)=f'(x)f'(x^(3))+f''(x^(2)) .Given that f(1)=1&f'''(1)=(1)/(4) ,then value of 4(f'(1)+f''(1)) is

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