Tyler Wallace's "Beginning Algebra Lab Notebook: Inequalities - Interval Notation"
Complete page 33 of Wallace's workbook to practice with interval notation. Try to complete this exercise before watching the video in this subunit, and then review the worksheet as you follow along with the video for solutions.
We use plots, graphs, and pictures to help us understand and communicate. Interval notation is a very visual way to communicate inequalities, and it also gives us visual techniques for solving them.
