`f(x^2)=x+10`,then f(4)=?

If f:R rarr R be a differentiable function such that f(x+2y)=f(x)+f(2y)+4xy, AA x,y in R , f(2)=10 , then f(3)=?

If f(x) a polynomial function satisfying f(x)f(y)=f(x)+f(y)+f(xy)-2 for all real x and y and f(3)=10 ,then f(4)-8 is equal

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

If f(x)= x^2+7x+10 then f'(2) =?

If f(x)= x^2+7x+10 then f(2) =?

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))atx=4 is
