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.

Any good introductory book in mathematics should cover this material, although I don't know of any resources where this is the primary focus. One excellent book that includes material on functions in the first chapter is Munkres' Topology, but it goes on to a lot of other topics that may not be relevant to you.
A good resource may be the Wikipedia pages on functions, and on bijection/injection/surjection.
