I am looking for exercises on functions which deal with one to one, onto, everywhere defined, inverse functions. Can anyone suggest me a book or source from the internet where I can find such problems.

Thanks.

    Most undergraduate real analysis and abstract algebra texts have problems like that in their chapters on foundations, fahad. Try Herstien's TOPICS IN ALGEBRA and Apostol's MATHEMATICAL ANALYSIS to start. And there are great problems on this in Paul Halmos' NAIVE SET THEORY.too.2011-09-11
