How to Analyze a Qualitative Graph

The video tutorial covers analyzing graphs using linear and nonlinear intervals, focusing on increasing and decreasing functions. It introduces key vocabulary and concepts, such as qualitative graphs, intervals, and constant rates. Through examples like climbing a ladder, a bike ride, and a road trip, the tutorial demonstrates how to identify different sections of graphs and interpret them in real-world contexts. The video also includes exercises for identifying increasing and decreasing intervals and understanding the relationship between time and distance in a skateboarding scenario.
