Monday - We discussed how to determine end behavior of a graph by looking at a graph and by looking at the leading coefficient and degree of the polynomial. We created a chart in our notes. You can download a copy of the chart by clicking
HERE
Then we looked at the 8 graphs we have been working with on all of our characteristics and learned how to identify the x and y intercepts graphically.
Tuesday - We learned how to find the x and y intercepts algebraically.
Steps to find the x-intercepts of a polynomial algebraically
- Set the polynomial equal to 0
- Factor the polynomial completely
- Set each factor equal to 0
- Solve each for the variable
Steps to find the y-intercept of a polynomial algebraically
- Replace all x with 0
- Simplify
We again took all of the equations that we have been looking at for the characteristics and used them to practice finding x and y intercepts. We used the graphs to confirm that we had solved correctly.
Wednesday - We learned how to use synthetic division and the Rational Root Theorem to solve polynomials for all zeros, also known as roots, solutions, x-intercepts.

Thursday and Friday were review days.
Thursday you had several graphs to look at and list all the characteristics that we have been working on. Unfortunately, I do not have a digital copy of the graphs. You also had an end behavior worksheet that you can click
HERE if you need another copy. Then there was also a page of polynomials to solve. I also do not have a digital copy of the 8 polynomials to solve. All of this work is due on MONDAY, Oct. 6.
Friday you will work on the review for the unit test. We still have some topics to cover but you can begin working on your review problems that we have covered and start your studying over the weekend. If you need another copy, you can click

The Next Test is Wednesday, October 8
