Algebra 2 Module 4 DBA
40 points 10 points each part
Part 1 – Application
Pick one of the two graphs below. Describe a situation which could be modeled by this polynomial graph. Be
sure to label the x and y axis with what each will represent in your real life graph. Sample labels could include
time, temperature, speed, distance and more. Be sure to add numbers to your axes as well and explain how
you came up with your situation.
Part 2 – Find the error(s) and solve the problem correctly.
Use synthetic division to determine if x +3 is a factor of the given polynomial.
If so, what are the other factors. If not, why not?
2𝑥
3
+ 7𝑥
2
+ 3
Answer:
-3|
2
7 3
-6 -3
2 1 0
Yes, since the remainder is 0 it is a factor. The other factor is 2𝑥 + 1
Part 3 – Discussion Question
How can synthetic division be used to find factors of polynomial functions?
Part 4 – Reflection
This question required:
1. What new information have you learned from this module? What surprised you about what you
learned? What knowledge from your past courses did you use in this module?
Choose 2 of the following questions:
2. Over the course of this module, what concept did you find the most challenging? What did you do to
clarify the concepts in this module to further your learning?How did I move through roadblocks or
challenges?
3. What was your favorite thing that you learned about this module? Why was it your favorite and give me
an example of a problem that you really understood and can’t wait to apply on the test.
4. Write a short story describing something that you did in this module of Algebra 2 that made you proud
of yourself.
5. The course resources and your teacher say that note taking is really helpful in mathematics. As you
went through this module would you agree or disagree with that? What additional advice would you
give to a student that is beginning the course today?”
Your response must be at least three paragraphs (1 per question you choose).
