=Algebra 2B - Spring 2012= =Mr. Bujak=

In an effort to be totally transparent and to support students 24/7/365.25, this volunteer-maintained and optional area is meant to be a collection of resources during the Spring 2012 semester "Algebra 2B" 0.5 credit course at Hope Charter High School. Applicable resources are also posted with each assessment in Power School Gradebook.

Algebra 2B Syllabus Algebra 2A Syllabus (PREVIOUS SEMESTER)

We have a class set of Casio fx300MS calculators - manual.

Textbook:

//Algebra 2//, Holt, Rinehart and Winston, 2003, ISBN 0-03-066054-8

There is also a 0.25-inch __//Algebra 2 Practice Workbook//__, ISBN 0-03-054084-4, with "Practice" worksheets. Worksheets will be provided to the students contemporaneously. These are provided below as links as are other appropriate worksheets and other resources for that concept/topic; including, but not limited to Warm-Ups, PowerPoint slides, scanned teacher notes generated during class, short videos, supporting Websites, etc.

All assignments will also have a reference link here in the applicable PowerSchool Gradebook daily assignment description.

Algebra 2 - Graphing Rational Expressions, Part 2 Here is the second installment on graphing rational expressions! This is part 2 of 2, covering vertical asymptotes, horizontal asymptotes, holes in the graph (point discontinuity), and factoring before graphing. Part 1 introduces horizontal asymptotes and graphs several examples.
