Let P be the rule which assigns each student (input) shown in the table to their parent's phone number (output). Is P a function? Why or why not?

• Yes, because each student has a unique phone number.

• No, because some students share the same phone number.

• Yes, because phone numbers are always unique.

• No, because students cannot be assigned phone numbers.

Let Q be the rule which assigns to each parent’s phone number (input) in the table above to the student’s name (output) associated with it. Is Q a function? Why or why not?

• Yes, because each phone number is associated with one student.

• No, because phone numbers can be associated with multiple students.

• Yes, because students have unique names.

• No, because phone numbers are not unique.

A school would want to use a student’s ID number to identify a particular student instead of their phone number because:

• Because ID numbers are unique to each student.

• Because phone numbers are easier to remember.

• Because ID numbers are longer than phone numbers.

• Because phone numbers change frequently.
