Let `f(x+y)=f(x)f(y)` for all `x,y in R` suppose that `f(3)=3,f(0)!=0` and `f'(0)=11,` then ` f'(3) ` is equal

Let f(x + y) = f(x) .f(y) AA x, y in R suppose that f(k) =3, k in R and f'(0) = 11 then find f'(k)

Let f(x+y)=f(x)*f(y)AA x,y in R suppose that f(3)=3 and f'(0)=11 then f'(3) is given by

Let f(x+y)=f(x).f(y) for all x and y suppose f(5)=2 and f'(0)=3. Find f'(5) .

If f((x)/(y))=(f(x))/(f(y)) for all x,y in R,y!=0 and f(t)!=0, if t!=0 and f'(1)=3 then f(x) is

Let f(x) is a differentiable function on x in R , such that f(x+y)=f(x)f(y) for all x, y in R where f(0) ne 0 . If f(5)=10, f'(0)=0 , then the value of f'(5) is equal to

Let f(x) be a differentiable function on x in R such that f(x+y)=f(x). F(y)" for all, "x,y . If f(0) ne 0, f(5)=12 and f'(0)=16 , then f'(5) is equal to

if f(x+y)=f(x)+f(y)+c, for all real x and y and f(x) is continuous at x=0 and f'(0)=-1 then f(x) equals to
