Welcome
It's embarrassing that nobody has welcomed you to Wikipedia and you have been using this account for years. Please feel free to contact me if you ever need assistance.

Regarding your question on partial function, it is answered by the image captions: the second diagram shows a total function. &mdash; Carl (CBM · talk) 22:18, 3 May 2010 (UTC)


 * Thank you for your Welcome and for your answer to my question, Carl. Regarding the latter, I was taught that the text of an article should always be complete, independent of any picture captions. --Timlevin (talk) 21:40, 21 December 2013 (UTC)
