The condition f(x + y) = f(x)f(y) f ( x + y) = f ( x) f ( y) only implies f(x) = ax f ( x) = a x for all rational numbers x ∈Q x ∈ Q and for some a ∈ R a ∈ R. You can get this equality for all real numbers if you have more conditions, for example, if f f is continuous in R R or if f f is Lebesgue-measurable. Share. Cite.

Conclusion: In saddle points calculus, a saddle point or minimax point is a point on the surface of the graph for a function where the slopes in perpendicular directions become zero (acritical point), but which is not a local extremum of the function. Mathematicians and engineers always have to find saddle point when doing an analysis of a surface.Web

View Solution. Q 2. Let f (xy)= f (x)f (y) for all x,y ∈ R. If f ′(1) =2 and f (2) =4, then f ′(4) equal to. View Solution. Q 3. If f (x+y) =f (x).f (y) and f (5) = 2, f ′(0) =3 then f ′(5) equals. View Solution. Q 4.f(x + f(y)) = f(x) + y f ( x + f ( y)) = f ( x) + y. really holds for all rational x x, it must therefore be the case that ( y) is always rational. Then we can proceed by considering particular x, y x, y, especially zero. That is, taking x 0 x 0, we get. f(0 + f(y)) = f(0) + y f ( 0 + f ( y)) = f ( 0) + y.

You could do that, but regardless, you would still have to find dx/dt (after writing out the chain rule). There are plenty of examples of chain rule where you could substitute functions like x(t) or y(t) into another function like f(x,y), yes it would make life easier and avoids chain rule altogether, however that doesn't teach you chain rule or the importance of it.Cho hàm số y = f(x) liên tục trên ℝ và có đồ thị như hình Gọi m là số nghiệm của phương trình f(f(x)) = 1 .
