Domain and Range of Linear Functions Practice
A practice set for 8th graders that builds fluency in identifying the domain and range of linear functions from graphs, sets of points, tables of values, and real-world contexts. It reinforces key terms and the three notations for writing sets (inequality, interval, and set-builder), and is well suited to a single class block or independent practice.

Teacher Guide & Tips
- Introduce the key terms (domain, range, and the three notation systems) as a brief whole-class warm-up before students work through the problems, which should take roughly 30 to 45 minutes.
- Discussion question: Why does a linear function that extends infinitely in both directions have a domain of all real numbers, while a set of plotted points has only a finite list of values?
- Scaffold for struggling readers: Have them first identify the leftmost and rightmost x-values (and lowest and highest y-values) on each graph or table, then convert those endpoints into inequality notation before attempting interval or set-builder notation.
- Extension for advanced students: Ask them to write a real-world context where the domain is restricted (such as time or quantity being nonnegative) and explain how the restriction changes the range.
