Unit 3: Cubic Functions
Lesson 9 of 13

Objective: SWBAT write an equation for a cubic function from a graph with given roots. SWBAT explain how the factor theorem helps them write a cubic equation.

Big Idea: How many points does it take to determine a cubic function? Four - and it helps if three of them are roots!
