Catalog Course Description

For students in technology programs who have had MATH 100 or one year of Beginning Algebra. Covers functions and graphs, properties of lines, the trigonometric functions, systems of linear equations, rational expressions, quadratic equations, solution of right triangles, vectors, integer exponents, linear regression, complex numbers, and an introduction to the graphing calculator. Requires a graphing calculator with the TI-84 Plus series recommended.

2. Solve application problems using a system of two linear equations.
1. Solve quadratic equations by factoring (whenever possible), using the square roots (whenever possible), and using the quadratic formula.
2. Solve applications involving quadratic equations.
11. Complex Numbers
1. Perform basic operations of addition, subtraction, multiplication, and division on complex numbers.
12. Regression Line or the Line of Best Fit
1. Use a graphing calculator to find the equation of the regression line or the line of best fit for a table of data.

### Assessment and Requirements

• A comprehensive final examination, weighted in the manner that it is worth at least fifteen percent (15%) of the final course grade, is required for all sections.
• Additional assessment of student achievement may include assignments, quizzes, and exams.
• Application problems must not only be included on chapter exams but also on the final exam.
General Course Requirements and Recommendations
• A graphing calculator is required of each student. The Mathematics Department recommends and uses the TI-84 Series.
• Application problems must be covered in all mathematics courses. Every section in any course outline that includes application problems must be covered.
