Unit 1, Day 2

Agenda

1. Number talk: Graph Talks — same axes, new question: which inputs are even allowed?
2. Launch your Math Journal — read Your First Entry and begin it
3. Random groups — four parents at the boards: $f(x)=x$, $x^2$, $\sqrt{x}$, $\frac{1}{x}$ — what can go in, what can come out?
4. Consolidate: Domain and Range — saying it precisely
5. Check your understanding: Domain and Range Practice, first block

Things to do before our next class

• Finish Your First Entry and read What a Strong Entry Looks Like.
• Journal: a function whose domain the real world restricts before the algebra gets a say.
