Bellwork reviewed graphing quadratics of the form y=ax^2+c and finding the LOS and Vertex of a quadratic.
The remainder of the period we discussed how to graph y=ax^2+bx+c and finding the maximum or minimum value of a function and when this value occurs (Sec 5-2).
Hwk #11 is due today.
Hwk #12 is due on Friday. Students are to use the sheet provided for Hwk #12.

Bellwork had students practice on ACT math questions.
The remainder of the period we discussed how the Standard Form of a Quadratic Function (Sec 5-1,2) can be used to find the Vertex, LOS, and the y-intercept. These were then used to graph a parabola using five points.
Hwk #11 is due tomorrow.

Bellwork had students practice skills they will be using during Chapter 5.
The remainder of the period we focused on the characteristics of Quadratic Equations and their graphs,Parabolas (Sec 5-1). We discussed the relationship between the Vertex and the Line of Symmetry (LOS).
Students also learned to find the equation of a quadratic given 3 or more points by either writing a system of equations and solving using matrices or by performing a Quadratic Regression.
Hwk #10 is due today.
Students were given the homework assignments for Chapter 5.
Hwk #11 is due on Wednesday.

No bellwork today.
Students took Test #1.
After the test students worked on Hwk #10 which is a preview of some terms and topics that we will be discussing in Sections 5-1 and 5-2.
Hwk #10 is due on Monday.

Bellwork had students investigate the graph of a parabola and how the graph is affected by changing some values in the equation.
The remainder of the period we continued this discussion on parabolas so that students could graph a parabola from a given equation and write the equation if the graph is given.
We also did some short review for tomorrow’s test.
No homework is due today.

Bellwork reviewed writing and graphing inequalities in order to maximize a certain quantity.
The remainder of the period students worked on some practice problems for Friday’s test.
Homework #9 due today.
Click on the links below for today’s bellwork and bellwork answers.
Bellwork had students explore graphs of absolute value functions.
The remainder of the period we discussed how changing the values in the absolute value equation y=a|x-h|+k affects the graph and how the graph could be created quickly by knowing these affects.
We also worked on an example problem from sec 3-4.
Hwk #8 is due today.
Hwk #9 is due tomorrow.
TOMORROW IS A LATE START.

Test #1 over sections 1-4, 1-5, 3-2 to 3-4, 3-6, 4-7, and 7-6 will be given this Friday, October 4, 2013
Students were given the review today, Sept. 30, and will be given answers to the review tomorrow Oct. 1.

Today’s bellwork was a lateral thinking problem that encourages students to be good listeners, questioners, and outside-the-box thinkers.
We then finished our discussion on Sec 3-4, Linear Programming by doing a few example problems.
The remainder of the period we reviewed some problems that will be on Friday’s Test.
Hwk #7 is due today.
Hwk #8 is due tomorrow(graph paper needed)
Hwk #9 is due Wednesday (graph paper is needed)
Test #1 Friday, students given review today.
Retakes for Quiz #1 must be completed by Friday.
