Unit 1, Day 14

Agenda

1. Random groups: run the definition on $f(x)=x^2$ at $x=3$, then at any $x$ at all — then let $x^3$ dare you
2. Consolidate: the derivative is itself a function — and the answers for $x^2$ and $x^3$ hint at a pattern worth naming
3. Task due: The Speed Camera — defend your verdict out loud, with Showing Your Thinking as the standard
4. Journal collection — Journal Checklist is your last look before handing in your Unit 1 volume

Things to do before our next class

• Journal (new volume): conjecture the derivative of $x^{17}$ without computing a single limit — and bring the conjecture.
