If `f(2x/y) = f(2x)-f(y)` for all `x,y gt0` and f(3) =2, then the value of `[f(7)]`, is

If 2f(x+y)=f(x).f(y) for all real x, y. where f'(0)=3 and f(4)=25 , then the value of f'(4) is equal to

Let f(x) is a polynomial satisfying f(x).f(y) = f(x) +f(y) + f(xy) - 2 for all x, y and f(2) = 1025, then the value of lim_(x->2) f'(x) is

If f(x+y) = f(x) f(y) for all x,y and if f(5) = 2 and f(0) = 3, then what is the value of f '(5)?

f(x+y)=f(x)*f(y) for all x,y anf f(5)=2,f'(0)=3 then f(5) will be

If f (x+y)=f(x)f(y) for all real x,y,f(2)=3,f'(0)=1 then what is the value of f'(2) ?

f(x+y)=f(x).f(y) for all x,yinR and f(5)=2,f'(0)=3 then f'(5) is equal to

If f(x+y)=f(x) xx f(y) for all x,y in R and f(5)=2, f'(0)=3, then f'(5)=

If f((x+y)/3)=(2+f(x)+f(y))/3 for all x,y f'(2)=2 then find f(x)

If f((x+y)/3)=(2+f(x)+f(y))/3 for all x,y f'(2)=2 then find f(x)
