# Algebra 2 Honors

## Our Week in Preview

We will continue to work on Quadratics.

Please be sure to upload your Cornell Notes and these must be your own handwritten notes. I am collecting notes to ensure that each student is participating in classroom lectures appropriately. Feel free to take pictures, but these must be supplementary to your own notes. A lot is said for writting out the solution with your own hand.

You are some of my favorite people!!

Learning Goals:

a. I can solve quadratic equations with real coefficients that have complex solutions.

b. I can use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.

Collaborative Practice: Work with your table groups to solve various quadratic equations that may have complex zeros using the process of completing the square.

First we will visit the learning scale which can be found on Canvas here. In the first check point, you will rate your confidence in each of the seven learning goals of this unit. Once you have rated yourself and saved the document to the appropriate folder in Notes Plus, please report your ratings using this google form so that I can collect class-wide data about our progress.

Today's Learning Goal (note the bolded sections):

I can identify the effect on the graph of replacing f(x) by f(x)+k, af(x), f(ax), and f(x+h) for specific values of a, h and k; find the value of these constants given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology.

Today's Learning Goal (Note the bolded part):

I can identify the effect on the graph of replacing f(x) by f(x)+k, af(x), f(ax), and f(x+h) for specific values of a, h and k; find the value of these constants given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology.

We will use the Desmos Online Calculator on the ipad to investigate the graphs of
1. y=2x^2
2. y=(1/2)x^2
3. y=3x^2
4. y=(1/3)x^2
5. *y=x^2 (the parent function)

Graph all of these on the same plane. What is the same about all of these? How are they different. Look at the a values and the corresponding graphs. What can you conclude about the value of a and the impact it has on the graph of the function? Save this image and your generalization in your notes.

We are also going to make a connection to our prior Learning Goal: Completing the Square and the Vertex Form of a Quadratic that we are currently working on. By the end of class, you will begin to be able to use the process of completing the square to transform a quadratic in standard form to vertex form.

You will take cornell notes today while I model some problems for you and you try some with your table groups. Please upload your OWN cornell notes to Canvas here. Remember, you must have all parts of the notes written by yourself. You may take pictures if you like, but they can only supplement your own written notes.

Remind me at 2:50 to stop instruction!!!
Last, we will visit the learning scale which is in your notes plus already but can be found on Canvas here. In the first check point, you will rate your confidence in each of the seven learning goals of this unit.
