Unit 1, Day 5

Agenda

1. Number talk: Which One Doesn’t Belong — four transformed cousins
2. Random groups — yesterday’s conjectures, stress-tested on parents your group has never graphed
3. Consolidate from the bottom: Transformations of Functions — one recipe, $y=af(k(x-d))+c$, for every function you will ever meet
4. Notes to your future forgetful self: stretch first, slide second
5. Check your understanding: Transformations Practice

Things to do before our next class

• Journal: explain to a Grade 10 student why $f(x-2)$ slides right, in words they would believe.
