If `f(xy) = f(x).f(y)` and `f(3) = 1`, then `f'(10)` is equal to

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

If f (x+ y) = f(x) , f(y) , f(3) = 3 , f'(0) = 11 . Then f'(3) is equal to

If f:R rarr R be a function such that f(x+2y)=f(x)+f(2y)+4xy, AA x,y and f(2) = 4 then, f(1)-f(0) is equal to

Given that f(x) is a differentiable function of x and that f(x) ,f(y) = f(x) + f(y) +f(xy) -2 and that f(1)=2 , f(2) = 5 Then f(3) is equal to

If f(x) is a function such that f(xy)=f(x)+f(y) and f(3)=1 then f(x) =

If f(x)f(y) + 2 = f(x) + f(y) + f(xy) and f(1) = 2, f'(1) = 2, then find f(x).
