Seeing functions in nature is a beautiful part of mathematics by analyzing the motion of a dolphin over time. Then take a look at the value of a stock and maximize the profit of a new toy. Explore the application of quadratics by emphasizing the key features of the graph. This is the tenth exercise in a 26-part series.

Instructional Ideas
- Give class members a copy of the graph of the dolphin to label with key features and their meaning based on the context
- Ask individuals to write a paragraph for each problem explaining the graph and the meaning of each key feature
Classroom Considerations
- Be sure students are comfortable with the notation used in the lesson or adjust to fit you class
Pros
- A distinct effort is made to ensure learners don't view the quadratic graph as showing the horizontal motion when the x-axis represents time
- Real-world examples are used that are familiar
- Handouts, keys, exit ticket, and a detailed teacher guide are included
Cons
- None
