Answer:
To determine if the relationship between the items ordered and the items delivered is a function, we need to know if each ordered item corresponds to exactly one delivered item.
A function, in mathematics, is a relation between a set of inputs (in this case, the items ordered) and a set of permissible outputs (the items delivered), with the property that each input is related to exactly one output.
If every item that was ordered was delivered exactly once, then the relationship is a function. However, if there are items that were ordered but not delivered, or delivered more than once, then it’s not a function.
Without specific data about the items ordered and delivered on day one, I can’t definitively say whether the relationship is a function. If you have more information or data, I’d be happy to help further!
