Interpreting Graphs of Functions

Mr. Mutter explains how graphs can tell stories by analyzing changes in direction and slope. He uses two examples: a temperature graph showing changes throughout the day and a distance graph depicting a journey with stops. Each graph is broken into parts, illustrating how different sections represent different story elements. Students are encouraged to creatively interpret graphs, considering axes and units to understand the narrative.
