If `f(x) = |x-2|-|x-4|`, then `f(x) = k` has

If f(x)=x+2, " then " f'(f(x)) at x=4 is

If f(x) = x +2, then f^(')(f(x)) at x = 4 is

If f(x)=x+2," then "f'(f(x))" at "x=4 , is

If f(x) = x+2 , then f'(f(x) ) at x=-4 is…......... .

If f(x)= x^(3)-kx^(2)+2x and f(-x)= -f(x), the value of k is_

f(x) is a polynomial funciton, f : R to R , such that f(2x) = f'(x) f^('')(x) Equation f(x) = x has

Let f(x)=2+x, x>=0 and f(x)=4-x , x < 0 if f(f(x)) =k has at least one solution, then smallest value of k is
