You must complete the in$-$class assignment before attempting this quiz. Some questions will come from the lecture notes and some from the assignment. You may use all posted lecture notes, any notes you have written down, and the work you completed for the daily assignment to answer the questions. You have $15$ minutes to answer the five questions. You may take the quiz twice, but the grades of the two attempts will be averaged, so if you do worse on the second try, your grade goes down.
