About the Lesson
This lesson involves observing how changing the values in a rational function affects the continuity of the graph of the function.
As a result, students will:
- Manipulate the factors of the numerator and denominator to observe the effects of each value.
- Explain how the values in a rational function determine the vertical asymptotes.
- Identify the conditions that must be met for a rational function to have removable discontinuity.
*Note: This activity contains an optional AP Practice Questions document for those students preparing for the AP Precalculus Exam.
