Answer:

A The relation (students, birthdays) is a function, but the relation (birthdays, students) is not.

Step-by-step explanation:

A function is a relation in which each input value, or x-coordinate, is mapped to one output, or y-coordinate. No x-coordinate can be used more than once.

The relation (students, birthdays) has students as the x-value and birthdays as the y-value. In order for this to be a function, each student would have to have only one birthday. This is true; no student has more than one birthday. This is a function.

The relation (birthdays, students) has birthdays as the x-value and students as the y-value. In order for this to be a function, each birthday would have to have only one student associated with it. This is not true; each birthday can have multiple people celebrating that day. This is not a function.
