Unit 2, Day 7

Agenda

1. Number talk: True or False — bold claims about $3^x$
2. Random groups — graph $2^x$, $3^x$, and ${\left(\frac{1}{2}\right)}^x$ on one board: what never changes?
3. Consolidate: The Exponential Function — domain, range, intercept, and the asymptote it never touches
4. Transform it — the recipe from Transformations of Functions arrives unchanged
5. Check your understanding — sketch two transformed exponentials and state domain and range

Things to do before our next class

• Journal: what $y=0$ means to $y=2^x$, in one honest sentence.
