Filed under: Homework — LEaddy at 8:26 am on Friday, February 25, 2011

I am attaching a file for you to practice on writing equations of circles and identifying the center and radius. This is due on March 3rd and 4th. 8-3 CIRCLE.HW

### Assessment for Chapter 8

Filed under: Algebra II — LEaddy at 3:36 pm on Wednesday, February 23, 2011

A quiz on the first three sections of chapter 8 will be given on Tuesday and Wednesday of next week. It will cover using the distance and midpoint formula, writing equations for the circle and parabola, and identifying the vertex, focus, directrix, axis of symmetry, and the direction of opening as well as transformations of parent functions.

### Chapter 8

Filed under: Algebra II — LEaddy at 9:16 am on Friday, February 18, 2011

We will start Chapter 8 next week.  The first section of Chapter 8  deals with finding the midpoint of a segment and the distance between two points using the formulas that you were introduced to in Geometry. The following chapters deals with Conics, i.e., parabolas, circles, ellipses, and hyperbolas. You will be required to write the equation for each conic and will receive a Conics project to complete as a test grade. Remember to continue to work hard.

Here is a file on finding the composition of functions.  Fxn_Comp_Inverse

### Operations and Inverse of Functions

Filed under: Algebra II — LEaddy at 7:17 pm on Tuesday, February 15, 2011

Operation of FunctionsYou are learning how to find the sum, difference, product, and quotient of functions as well as how to find the inverse of a relation and function.

I am attaching extra notes on these concepts. You will receive instruction on next class on finding the composition of functions.  Remember to continue to review your notes daily.

### 3rd nine weeks

Filed under: Algebra II — LEaddy at 3:50 pm on Thursday, February 3, 2011

This nine weeks we will begin to discuss have to evaluate, graph, and identify end behavior of polynomial functions.  We reviewed how to solve quadratic equations by factoring, completing the square, and using the quadratic formula. It is important that you put your best effort forward for the remainder of the school year. Complete all homework assignments, study for quizzes and tests, and attend the tutoring session on Tuesday and Thursday from 2:20-3:30.
