Draft talk:Specifying a function

Moved from the draftpage. "Sometimes<-- I had used this word in my first change. The reason why I later changed got rid of it is because it could suggest to some readers that sometimes a formula cannot be given. And is that really possible? Is it possible to define a function that cannot be given by a formula? No "closed-form" adjective in the previous sentence, just 'formula'. Cactus0192837465 (talk) 23:27, 28 January 2019 (UTC),"
 * Ok. I admit that's a good point. As other have noted, the problem is that English is ambiguous... Maybe it's clearer to say what we meant to say, instead of trying to paraphrasing it (please see my edit). -- Taku (talk) 23:49, 28 January 2019 (UTC)
