In reading out about topological spaces and topologies I noticed that they do not give much specific examples, so I have not found an answer to the following simple question:
Can we use the same function for mapping into two different open sets of a given topology? Or, perhaps equivalently, can we pick as the domain of a function, the union of two open sets of a given topology?
