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???
