Exponential Functions Project

Scenario Examples

You need to:

• Independent Variable
• Dependent Variable
• Boundaries - where do you think it starts and stop
• Starting Point
• Growth/Decay Rate

1. Pick a scenario or create your own scenario. 2. Write an equation to represent the exponential function 3. State why it is an exponential function. 4. Create a table to represent the exponential function- Identify the growth/decay rate on your table. - Explain how the growth/decay rate represents an exponential function.5. Create a graph to represent the exponential function 6. Use color to connect and identify “a” and “b” in the table, equation, graph, and scenario. 7. Identify the following:
