If f: R -> R, where R is a real line, then thinking of f as a machine
that you put one number into and receive another out is adequate. In
fact, I can't think of anything better than that. There may be some
simple formula associated with matching the input with the output, or
not. I don't know if they also need to know what is injection,
surjection and bijection, but that comes after the basic definition.
