Ch 7: Praxis I Math: Functions

Praxis I Math: Functions

Your video instructors will give you an in-depth explanation of the lesson topics, while also offering you advice on how what you learn can best be utilized on the skills test. You'll find that the variety of learning approaches you're exposed to might make the chapter more interesting and can fully prepare you to take the skills test.

This chapter is designed to help you learn more about functions and prepare for the geometry and measurement section of the skills exam. Topics for your video lessons will also include:

• Identification, notation and practice problems
• Domain and range
• Adding, subtracting, multiplying and dividing functions
• Composing functions
• Using function operations to practice problems
• Manipulating functions and solving equations
• Graphing functions

Objectives of the Praxis I Math: Functions Course

The pre-professional skills test is intended to get an idea of the mathematical ideas and skills that a college-educated adult might need in addition to measuring their ability to solve problems. Other geometry and measurement topics on the Praxis include geometric properties, systems of measurement and the xy-coordinate plane.

Once you've completed this chapter, you'll be better prepared for the geometry and measurement section of the exam, which composes about 22.5% of the full exam. Usually there are ten multiple choice questions on the Praxis I related to geometry and measurement. You'll be allowed 75 minutes to complete the test.

The self-assessment quizzes are designed to measure how well you can use the testing methods you've learned and to give you a glimpse of how questions are designed on the actual test.
