What does the empty function evaluate to, for a particular set A?--ASL 00:51, 8 July 2007 (UTC)[reply]

Since the empty function has an empty domain, the empty function doesn't "evaluate to" anything. Paul August ☎ 02:10, 8 July 2007 (UTC)[reply]

I just wasn't used to defining a function in terms of a graph (which is a set, and therefore may be empty)--ASL 21:03, 8 July 2007 (UTC)[reply]
