Unit 2, Day 12

Agenda

1. Number talk: True or False
2. Random groups — higher-order derivatives: $f^{\prime }$, $f^{\prime \prime }$, $f^{\prime \prime \prime }$ of the same function, and what each one is the rate of change OF
3. Consolidate: the second derivative as the rate of change of a rate of change, in words before symbols

Things to do before our next class

• Journal: an everyday quantity whose second derivative you have felt.
