WebA function that solves this equation is called an additive function.Over the rational numbers, it can be shown using elementary algebra that there is a single family of solutions, namely : for any rational constant . Over the real numbers, the family of linear maps:, now with an arbitrary real constant, is likewise a family of solutions; however there can exist other … Web9.

Visit Stack Exchange WebStep 1/3. (a) To determine the critical points of a function, the points where the gradient of the function is zero or undefined should be found. The gradient of f ( x, y) is given by ∇ f ( x, y) =< 4 x 3, 4 y 3 >. At ( 0, 0), the gradient is zero, since 4 x 3 = 0 and 4 y 3 = 0. Therefore, ( 0, 0) is a critical point. View the full answer.
WebTake $y=0$ to get $f(x, z) = f(x, 0) + f(x, z)$, so $f(x, 0) = 0$. $f(x, y) = g(x+y) - g(x)$ is a solution for arbitrary functions $g$. I don't know if those ar
