Hi everybody,
I guess most of you know how a function is defined from a set A to a set B. How do we prove that many different functions exist (usually, if sets A and B are for example R) from A to B? Of course we can come up with many different functions, real ones for example, but is there any other way of proving that the set of real functions for example has infinite elements?
Thanks
