its definitely not A because thats a one-to-many relation which is not a function

phi · Answer

if you are given the student's name, then you know the name of his/her favorite math teacher.  As long as there is only *one* teacher named per student, you have a function.

set A has lots of colors, and to be a function, it has to be only *one* color.
so A is not a function.
