Unit 1, Day 10

Agenda

1. Number talk: Which One Doesn’t Belong — four difference quotients
2. Random groups — derive the derivatives of $x^3$, $\sqrt{x}$, and $\frac{1}{x}$ from the definition
3. Consolidate: the pattern in the polynomial results, spotted rather than announced

Things to do before our next class

• Journal: the algebra step where the $h$ cancels, in your own words.
