We mostly looked at the recent test from last week.

It had problems with critical numbers. Numbers that lead to vertical asymptotes are also critical numbers. The second derivative was also used a few times.

When an expression is multiplied or divided by a constant, the constant doesn’t disappear, but it doesn’t change the process too much. The constant is simply still there as it was later on.

Also looked a word problem at the end. Would be good to review the quotient rule next time.
