Let assign each student at your school to a grade level.
a. is this an example of a function? explain your reasoning.

Yes, it's an example of a function.

Step-by-step explanation:

In order to answer the question, you have to know the definition of Function.

A function is a relation between sets that assigns to every element of the input set exactly one element of the output set.

Therefore, if you have a relation that assigns each student to a grade level then you can consider it a function because each student (input set) is assigned to a grade level (output set).

Every student is in a grade level, therefore the relation assigns to every student exactly one element of the output set (one grade level)
