Question

the relation described in this statement can be classified as which of the following: a function, a relation, both a function and a relation, or none of the above. statement: the number of ice creams sold on a given day and the temperature.

Answer 1

The answer is  a relation.
It is possible for the number of ice creams sold to be the same on multiple days and it is possible for the temperature to be the same on multiple days. Thus we will have situations where the domain value maps to multiple range values, which is not a function.
