In this lesson, we learned how to graph absolute value functions by using transformations. We reviewed the concept of absolute value as the distance from zero on a number line and how it can be represented algebraically. We also explored how to graph absolute value functions using a T-table and identified the domain and range of these functions. Finally, we applied these concepts to a real-life scenario of a hot air balloon ride to determine its maximum height and the time it takes to reach that height.
