If `f(1) - 1, f'(1) = 3`, then the value of derivative of `f(f(f(x)) + (f(x))^(2)` at `x = 1` is

If f(1) = 1, f'(1) = 3, then the derivative of f(f(x))) + (f(x))^(2) at x = 1 is

If f(1) = 1, f'(1) = 3, then the derivative of f(f(x))) + (f(x))^(2) at x = 1 is

If f(1) = 3 ,f'(1)=-1/3 , then the derivative of {x^(11) +f(x)}^(-2) at x = 1 is

If f(1) = 3, f' (1) = -1/3 , then the derivative of {x^11 + f (x)}^-2 at x = 1, is

If f(1)=1,f^(')(1)=3 then the derivative of y=f(f(f(f(x)))) at x=1 is M .Then the value of |(M)/(9)-1| is

If f(1)=3,f'(1)=-(1)/(3), then the derivative of {x^(11)+f(x)}^(-2) at x=1, is

If f(x)=(x+1)/(x-1) , then the value of f(f(2)) is

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

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

If 2f(x).+ 3f(-x) = x^2-x+1, find the value of f(1).
