Example ¥: InterpretingGraphs This graph shows someone taking a walk in the neighborhood. Describe what it shows by labeling each part.
Graph I indicates a quantity that does not change with time. Graph II shows an increase over time. Example 1: Analyzing Graphs Which graph in Example 3 could show a car sitting at a stoplight? How do you know? A car sitting at a stoplight would stay in the same place over time. Graph I could show a car sitting at a stoplight.
Example 3: Sketching a Graph A pelican flies above the water searching for fish. Sketch a graph of its altitude from takeoff from shore to diving to the water to catch a fish. Label each section.
