Math 112 syllabus

Precalculus Algebra

Course Description:  Covers algebraic, graphical and numerical properties of functions, focusing on linear, quadratic, general polynomial, absolute value, rational, exponential, and logarithmic functions. Topics also include equations, inequalities, and complex numbers. Applications of mathematics to modeling real world situations are emphasized. Credit for both MA 112 and MA 115 is not allowed. Core course

Prerequisites:  C or better in MTH 100 or a sufficient Mathematics Placement Exam score or a sufficient ACT Mathematics subscore.

Textbook:  A custom edition for the University of South Alabama. Taken from: Precalculus: A Right Triangle Approach, Fifth Edition by Judith A. Beecher, Judith A. Penna and Marvin L. Bittinger (2016). ISBN 9781323102879 This is a hole-punched loose-leaf format available at the USA bookstore shrink wrapped with an access code for MyLabsPlus.

***Buyer Beware Note***

The required materials for this course should be purchased at the campus bookstore. A tutorial program called Mymathlab will be a required component of this course and access will be through MyLabsPlus. The technology program will give you access to a complete e-book, on-line tutorial assistance with homework problems, access anytime video help, and incorrect answer analysis and feedback. The price of the bundled textbook and the MyLabsPlus access code is available as a very cost-effective solution for this course. 

There are two warnings to consider:

1)      If you decide to rent a textbook or buy a used copy, you will also need to purchase the tutorial and homework access card separately. The separate code is available for purchase in the bookstore or directly from the publisher. However, please note that the combined cost of the rented/used book and the access code may be more expensive than buying the new book/access code bundle in the bookstore.

2)      I strongly suggest that you do not purchase your codes from any person or site other than the bookstore or Pearson. Many of the codes sold on Amazon Marketplace and like sites can be defective or already activated and will not work. You will then need to purchase a second code, causing greater expense.


Calculator: A Texas Instruments TI30XII-S scientific calculator is required.

Coverage: Chapters 1 – 5 (omitting 2.6).

Learning Objectives:

  1. Recognition of function model groups by name, equation and general graph shape:  linear, quadratic, cubic, general polynomial, rational, exponential, and logarithmic.

  2. Vocabulary used to describe graphs:  domain, range, increasing, decreasing, x- intercept, function zero, y-intercept, maximum, minimum, asymptote, vertical, horizontal, axis, scale, coordinates.

  3. Real number line and solving inequalities to describe number sets on that line.



The course has an online homework component using MyMathLab.
