I like to know if it is consider non-simplicity if we use symbol like
to speak about a function (f between the sets X, Y), here in the simple english zone. Can anyone can help me? --kidd 06:46, 31 December 2006 (UTC)
- I think it's simple. It is not a complex English word. Also, it's simple to explain. I just replied to something written in 2006. πr2 (t • c) 01:20, 11 November 2011 (UTC)
I think we are talking about a crowd who does not speak a (natural) language well. Mathematics has its own language, which is pretty universal, probably; the symbols used (uppercase, bold letters for sets) are probably agreed upon too. Big question: would someone in Thailand, or Japan use the same basic symbols, even though they use a different alphabet? - I think the gist is to explain well, not to not use the common symbols/language of mathematics. --Eptalon (talk) 20:22, 4 April 2012 (UTC)
Can a mathematician help out? We've been studying the Y-output as "Range", not "Codomain". I didn't go ahead and change it because I didn't want to cause some edit war. Anyways, restating it, our Alg class describes what simple.wikipedia calls "Codomain", "Range". Is it different for some Algebra classes? Is it a regional/country thing? Thanks, --Atcovi (talk) 14:00, 10 December 2016 (UTC)
- Range can mean two different things. It can mean the codomain, but it is most commonly is talking about the "image" of the function (see article). The difference? A codomain refers to all of the possible solutions of a function, while the range refers to the specific set of outputs related to your inputs. Let me know if I don't make sense!

- Yes that makes perfect sense !

- Codomain vs Range
- The Codomain and Range are both on the output side, but are subtly different.
- The Codomain is the set of values that could possibly come out. The Codomain is actually part of the definition of the function.
- And The Range is the set of values that actually do come out.
