1. Cubic Functions f(x) = x³
Unit 1 Lesson 5

2. What is a cubic function?
Working with your pairs partner, complete the graph of f(x) = x³.
Answer the questions in the boxes and be prepared to share.
Share…

3. What happens when f(x) = x³ + b?
With your pairs partner, complete the Families of Cubic Functions Handout for f(x) = x³ + b.
Be prepared to share your findings.
Share and discuss…

4. What happens when f(x) = ax³?
Complete the Families of Cubic functions handout for f(x) = ax³.
Yes…be prepared to share!!!

5. What is “end behavior”?
The end behavior of a function’s graph is the behavior of the graph as x approaches positive infinity (+∞) or negative infinity
(-∞).
If the degree of the function is ODD and the leading coefficient is positive:
f(x) → -∞ as x → -∞ and
f(x) → +∞ as x → +∞
