What is a Function???

Let's try and get a good definition of a "Function" going....everybody please feel free to contribute.....

So far I have...


A variable related to another so that for each value assumed by one there is a value determined for the other. The function is the relationship between the two.

or/and...

A rule which relates two sets together so that there is a unique element in the second set assigned to each element in the first set. 



Opinions???
