I always feel weird posting yes or no questions because in short someone ultimately answers the question with a simple 2 or 3 letter word and then I'm choosing a correct answer that didn't really give me any insight other than a confirmation that I did something right... Is there a way that I can just not choose a correct answer and let the question serve as an example for someone else down the road that may be stuck? Also are yes/no questions generally frowned down upon?
Related: Asking questions with very short answers. The consensus there was that such questions are fine.
That said, don't you also want to know why the answer is yes or no? Also, you may be interested in a more general statement than a simple yes/no for a particular example. For instance, along with the yes/no question
you could ask
More generally, for which numbers $c$ is it true that $c\min(x,y)=\min(cx,cy)$?
