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

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

If (x)=(x^(2)-4)-:(x-2) f o rx <2,f(x)=4 for x=2 and f(x)=2 for x<2, then f(x) at x=2 is

If f(x)=|x-2|" and "g(x)=f(f(x)), then for 2ltxlt4,g'(x) equals

If f(x)=|x-2|" and "g(x)=f(f(x)), then for 2ltxlt4,g'(x) equals

If f(x) = 4x - x^2 , then f (a + 1) - f( a - 1) =

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

If f(x)=|x-2| and g(x)=f(f(x)), then for 2

If f(x) = 4^x/(4^x + 2) , then find f(x) + f(1 - x).

If f(2-x)=f(2+x) and f(4-x)=f(4+x) for all x and f(x) is a function for which int_0^2 f(x)dx=5 , then int_0^(50)f(x)dx is equal to
