1. The problem states that the function $F(x,y)$ is equal to 10 for all values of $x$ and $y$. 2. This means $F(x,y) = 10$ is a constant function. 3. A constant function does not depend on $x$ or $y$, so it remains the same regardless of the input values. 4. Therefore, the function $F(x,y)$ is simply: $$F(x,y) = 10$$ 5. There is no further simplification or evaluation needed since the function is constant. Final answer: $$F(x,y) = 10$$
