Real Life Example of a Function: Each person that has a SSN is an example of a function because each person (domain) would correspond to one unique SSN (range). No domain would have more than one range in this case thus making it a function. Real Life Example of not a Function: A mother as it relates to her children is not an example of a function because the mother (domain) is one member and relates to her children (range), she could have 2 children and thus that domain would match to more than one member of the range....
