2-3 Interpreting Graphs I can I c match real world situations to graphs create a graph that matches real life situations to graphs tell the difference between discreet and continuous points an match real world situations to graphs. Learning Target:

2-3 Interpreting Graphs Vocabulary Discrete Points: Continuous Points: data points that can be only specific values ex: number of kids in a class data points that can take any value ex. temperature

2-3 Interpreting Graphs The graphs show the speeds of two cars over time. Tell which graph corresponds to each situation. Graph 2 Graph 3 Example 1 – this is NOT on your note sheet! Time Speed Time Speed Mr. Lee is traveling on the highway. He pulls over, stops, then accelerates rapidly as he gets back on the highway. Graph 3

2-3 Interpreting Graphs The graphs show the speeds of two cars over time. Tell which graph corresponds to each situation. Graph 1 Graph 2 Example 2 – this is NOT on your note sheet. Time Speed Time Speed Ms. Montoni slows down as she leaves the main road. She continues to slow down as she turns onto other streets and eventually stops in front of her house. Graph 1

2-3 Interpreting Graphs Example 3 – Do this on your note sheet. Tell which graph corresponds to the situation described below. Time Runner ’ s Speed Time Runner ’ s Speed Time Runner ’ s Speed Graph 1 Graph 2 Graph 3 Melissa builds up her speed during the beginning of the race. She maintains her running speed for the remainder of the race. Graph 1—Melissa ’ s speed increases at the beginning and then the graph remains constant.

2-3 Interpreting Graphs Create a graph for the situation. Tell whether the graph is continuous or discrete. The table shows the temperature inside a car over time. Time 8:00 8:30 12:00 12:30 Temp.(F) Car Temperature Time Temp (F) ‏ The graph is continuous. Example 4

2-3 Interpreting Graphs Create a graph for the situation. Tell whether the graph is continuous or discrete. A market sells pumpkins for $5 each. Pumpkin Cost Pumpkins Purchased Cost($) ‏ Example 5 The graph is discrete.
