lf `| f(x) + 6-x^2| =| f(x)|+|4-x^2| + 2`, then f(x) is necessarily non-negaive for

If |f(x)+6-x^(2)|=|f(x)|+|4-x^(2)|+2 then f(x) is necessarily non-negaive for

If f(x)=|x^(2)-5x+6| then f'(x) is equal to

If f(x)=|x^(2)-5x+6|, then f'(x) equals

If f(x)=2x^(6)+3x^(4)+4x^(2) , then f'(x) is

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

The remainder when f (x) is divided by f (x) is f(-(3)/(2)) , then g (x) is necessarily 2x+3 [ True/False]

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

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

If f(x)=(2x+3)/(x-2) , then: (f@f)(x)=
