Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function. The domain is the set containing all the students names.
A relation represents a function when each value of the input is mapped to only one value of the output.
For this problem, we have that:
Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
The domain of a function is the set that contains all possible input values for the function, hence the domain is the set containing all the students names.
