Today we took some time to review the features of graphs that we had been looking at for a little while now. We have learned about intervals, increasing and decreasing intervals, intervals where graphs are concave up or down, local maximum and minimums, end behavior, and roots/zeros of graphs.
Today we focused on the graphs of cubic (3rd-degree) polynomial functions and learned about different features of those graphs, like how to write when they increase/decrease, what “local maximum” and “local minimum” points are, and how those are different than “absolute maximum” and “absolute minimum” points.
Homework is below. Check the Agile Mind calendar to view the slides from today if needed.
Today we practiced what we’ve learned so far with polynomials. Homework is #1-10, and it is suggested you go through #11-14 using something like wolframalpha.com to graph the functions as shown below. #11-14 will let you get a leg up for the next few days.
Today we had an introduction to polynomials. Some of you may already know about polynomials from Algebra 1, and that is great! We are going to be reviewing what they are and building upon that Algebra 1 knowledge in this class.
In Agile Mind, we started with Topic 4: Introduction to Polynomials, go to the “Overview” section and we did all 3 pages online.
Today is the last review day before the Topic 3 Test. In class, we worked on the study guide on the Agile Mind website, dearborn.agilemind.com.
We also took some time to reflect on which parts of the unit we feel the best with and which parts we need the most help with. Reflect on your own feelings and keep this in mind when studying tonight. Make sure you are focusing more on the types of questions you feel you need the most practice on, and know that you can spend a little less time on the ones you already know well.
For the study guide, make sure you go to the “My Agile Mind” tab at the top of the page, then go to your “Calendar”, then click on the “Topic 3 Study Guide”. You can complete this multiple times, which I recommend.
Today we used student.desmos.com to graph parabolas that matched what we saw on our screens. From this, we were reinforcing what the “a”, “h”, and “k” values do to our graph. Remember to look back in your notes to see where those values are in the equations and what they look like when we write it out.
If you didn’t complete the assignment, you can still finish it if you go to
Today we mostly were practicing with transformations on Agile Mind. We were reminded what the values of “a”, “h”, and “k” do to change a graph and we tried to fit graphs to match some data using those transformations.
Today we learned more about transformations and what those change about the equations. We learned that if we shift a graph horizontally, the addition or subtraction would be inside the parentheses, but if we shift vertically, the addition or subtraction would be outside the parentheses.
