### About This Chapter

## ORELA Mathematics: Continuity of a Function - Chapter Summary

This chapter has been assembled to help you review what you know about continuities of functions as you prepare for the ORELA Mathematics exam. Watching these lesson videos will refresh your knowledge of:

- Continuities of functions
- Discontinuities of functions
- Graphs and discontinuities of functions
- Continuity regions

These are online lessons that can be reviewed whenever you have a spare moment. Take them with you via a mobile device and learn even when you're on the go. Reinforce your understanding of continuities by completing the quizzes that accompany the videos.

### ORELA Mathematics: Continuity of a Function Objectives

The ORELA Mathematics exam contains questions in a multiple-choice format. It is administered by computer and should be completed within four hours and 15 minutes. Worth 19% of the 150-question exam, the 'Trigonometry and Calculus' content domain includes questions about continuity. Use this chapter to refresh your knowledge of continuities so that you will be prepared for these types of questions on test day.

### 1. Continuity in a Function

Travel to space and explore the difference between continuous and discontinuous functions in this lesson. Learn how determining continuity is as easy as tracing a line.

### 2. Discontinuities in Functions and Graphs

In this lesson, we talk about the types of discontinuities that you commonly see in functions. In particular, learn how to identify point, jump and asymptotic discontinuities.

### 3. Regions of Continuity in a Function

Can Earth ever compete with extraterrestrial UFOs? In this lesson, you'll learn that not all functions are continuous, but most have regions where they are continuous. Discover how to define regions of continuity for functions that have discontinuities.
