Problem #1
Answer: C
The situation cannot be modeled by a function. Looking at the tables below, if the towns represents the x-values, students from Naperville could attend either Central or North, causing an x-value to be paired with more than one y-value. The same thing happens if the schools represent the x-values. There are students from both Lisle and Naperville that attend both schools.

Problem #2
Answer: A
The frames would have to represent the domain. For example, there are not repeating frames. meaning in each game of bowling there is one frame one, one frame two, one frame three, and so on.


Problem #3
Answer: B
In order for the situation to be represented as a function, students would have to be the inputs. Each student is unique, which would mean there would be no repeating inputs. If the grades represented the inputs, it would be possible for more than one student to be paired with a grade. For example, using a grade of "82%" as an input, there are multiple students (or outputs) that could have the same grade. Therefore, grades cannot represent the inputs, they have to represent the outputs.
