**PLACEMENT REQUIREMENTS**: Math 107 or ACT Math Score of 23-25, or KC
Asset Exam Score of 41-55 on Int.Alg. test

**COURSE DESCRIPTION**: This course will consider basic algebraic operations
and expand their use to cover major topics of factoring; working with exponents;
solving equations, including linear, quadratic and systems; graphing; and
functions.

**TEXTBOOK**: __College Algebra__, by Larson, Hostetler (7th edition,
2007)

**EVALUATION**: Five 50-minute exams will be given during the semester.
**100 pts.** Each.

Test 1 | Chapter 1 (sec. 1.4 – 1.7)
Quadratic Equations and InequalitiesChapter 4
(sec. 4.3 - 4.4) Conics |

Test 2 | Chapter 2 Functions and
Graphs |

Test 3 | Chapter 3 Polynomial
Functions |

Test 4 | Chapter 5 Exponential and
Logarithmic FunctionsChapter 6 Systems of Linear
Equations |

Test 5 | Chapter 7 Matrices and
Determinants |

Homework and announced/unannounced quizzes **100 pts**.

The lowest exam score may be dropped

Thus, TOTAL POINTS FOR THE CLASS would be **500 pts**.

Grades will be assigned as follows:

450 – 500 A, 400 – 449 B, 350 – 399 C, 300 – 349 D, below 300 F

**CHEATING POLICY**: If caught cheating in any way, the student
will receive an F for the final grade.

**SUPPLEMENTARY MATERIAL**:** **

The College Enhancement Center @ Kaskaskia College does tutoring 8-5pm, Monday
through Friday

**RECOMMENDED SUPPLEMENTAL WEB SITES:**

The
following web sites will be extremely helpful with many of the concepts of
college algebra. I highly recommend you visit and try these sites
out.

**Geocities.com**(http://www.geocities.com/CapeCanaveral/Launchpad/2426/index1.html)

You need to scroll down and select pop up menu to see index to lessons and practice quizes on a wide variety of college algebra concepts. This is a must see site. Highly recommended for you to see what is available.**Purplemath.com**(http://www.purplemath.com/modules/index.htm)

Scroll down to advanced algebra topics to find help with an extremely large variety of college algebra concepts. You should review this site to observe what topics are covered and note when you will need them.**Expage.com**(http://expage.com/teachermathpage)

Scroll down to the all about algebra link to access a wide variety of useful algebra links.**Sosmath.com**(http://www.sosmath.com/algebra/algebra.html)

This site provides explanations on quadratic functions (completing the square, quadratic formula, etc), composite functions, etc. Scroll down to see the index of lessons. You can also get some good explanations on factoring as a review for chapter 1 of the text. There are also lessons on rational functions, polynomial functions, inverse functions, exponential functions, and logarithmic functions.

**ATTENDANCE POLICY**: To be successful in a math course, attendance would be
very important, almost critical. If more than two weeks of classes are missed
without a valid excuse ( death in family, hospitalization, nuclear blast, etc.)
I reserve the right to withdraw you from class with an F. If you know in advance
that you cannot attend class on a certain day, you may possibly get my prior
approval. __There are no make-up exams or quizzes__. If you come to class
late, you will **not** receive extra time for exams or quizzes. You must take
the Final Exam (test 5) to have your lowest test score
dropped.
