Course Description and Competencies

What to Expect

In this course, you will learn how to use algebra to model real-world data. You will use functions, graphs, models, and other math skills to understand the information in authentic and meaningful ways. The material includes readings, interactive graphs, as well as learning checks and quizzes. Learners should complete Applied Probability and Statistics or its equivalent prior to engaging in Applied Algebra. 

Course Competencies

This course covers the following competencies:

  • Analyze graphical depictions of real-world situations using functional properties.
  • Apply linear functions and their properties to real-world problems.
  • Apply polynomial functions and their properties to real-world problems.
  • Apply exponential functions and their properties to real-world problems.
  • Apply logistic functions and their properties to real-world problems.
  • Verify the validity of a given model.
  • Interpret the real-world meaning of various functions based on notation, graphical representations, and data representations. 

Assessment

The assessment provides an opportunity to demonstrate your mastery of the competencies in this course. You may attempt the assessment two times before additional support is necessary. If you require further attempts, please contact your Student Experience Team.

Technology Requirements

We want you to have the tools to succeed! Since this course includes at least one proctored test, please be sure to have a working microphone, speakers, and an external webcam. Unfortunately, an internal webcam (built into many laptops) is not acceptable. (Note: The external webcam is required only for exams that have proctors. You do not need one for practice tests and other non-proctored assessments.) If you haven't already, be sure to download the Meazure Learning Guardian browser, which you will need for the proctoring system.

You will need Adobe Acrobat Reader DC. If you haven't already, download this free software. You may encounter an interactive form that contains fields that you can select or fill in. Review how to fill in a PDF form.

You are allowed to use a hand-held calculator on every assessment. Be sure to follow these calculator requirements.

For other details about the technology you'll need, review the Computer System and Technology Requirements. If you have questions about your setup, contact support@academy.wgu.edu.
