What kind of functions have holes in their graphs? Here, the teacher guides the class on how to use the simplified function of a rational function to aid in the graphing of the original rational function. T-tables are used in order to help find the point of discontinuity of the rational function. The lesson plan provides questions to use in order to determine the class's understanding.

Instructional Ideas
- A projection device would be beneficial to project the guided practice pages as the teacher works them
Classroom Considerations
- Emphasize that all rational functions do not have the denominator as a factor of the numerator
- Point out that when the denominator is a factor of the numerator, the rational functions will simplify to a polynomial that can be graphed fairly easily
Pros
- Warm-up problems are provided that relate the skills needed in order to be successful in the lesson
- Answers are provided for worksheet, along with informal assessment questions
