let be the functional equation f(x,y)=g(r(x)+h(y)) my question is..does this equation have a solution?..thanks...

The functional equation f(x,y) = g(r(x) + h(y)) has a solution, as established in the discussion. By defining g(x) = x, r(x) = x, and h(x) = x, the equation simplifies to f(x,y) = x + y. To find a unique solution for f(x,y), it is essential to identify the appropriate functions r(x) and h(y) that satisfy the equation. This approach confirms that the functional equation can indeed be solved with the correct function definitions.
