I don't like the title 'injections are invertible'. To me invertible means to have an inverse, (what the paragraph I am critisising calls a 'full inverse').

I would prefer something like 'injections have left inverses' or maybe 'injections are left-invertible'. Then the section on bijections could have 'bijections are invertible', and the section on surjections could have 'surjections have right inverses'.

I don't like that the main heading of this article is "Injective function" and not "One-to-one function". I am not a PHD or anything, but it seems to me that one-to-one function is the term that is used within highschool and college mathematics, not "Injective function".
