If `f` is a differentiable function such that `f(xy) = f(x) + f(y) : x, y in R`, then `f (e) + f(1/e)` is

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)=?

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(2)=1 then f(x)=

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

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

If f(x) be a differentiable function,such that f(x)f(y)+2=f(x)+f(y)+f(xy);f'(0)=0,f'(1)=2 then find f(x)

Let f(x) be a differentiable function satisfying f(y)f(x/y)=f(x) AA , x,y in R, y!=0 and f(1)!=0 , f'(1)=3 then
