I've learned that the difference between domain and range is.....domain is the set of possible X values and range is the set of possible Y values. also, a domain is the values that a function maps "from" and the range is the values that a function maps "to"

I am having difficulty describing a real-life situation that could be modeled by a function.

HELP!!!

How about rainfall during a year? The number of births at a hospital during a year? How about the relationship betwen height and weight as a child ages? The amount of calories consumed daily vs. weight? Adult weight vs. running speed? (Do I seem consumed with concern over weight?)

Although this is not my area of expertise, I hope this helps. Thanks for asking.
