In this lesson, you learned how to:
- Use function notation to write equations that represent exponential relationships.
- Determine whether the relationships in descriptions, tables, equations, or graphs are functions.
Here are the activities that helped you reach those goals:
- 5.8.1: Meaning of a Function Presented Graphically
- In this activity, you reviewed the meaning of a function presented graphically. Interpreting the graph in terms of the context helped prepare you for your work with functions in the rest of the unit.
- 5.8.2: Represent a Function as a Table of Values, Graph, and Equation
- In this activity, you represented a situation using a table of values, a graph, and an equation.
- 5.8.2: Self Check
- 5.8.2: Additional Resources
- 5.8.3: Using Function Language and Notation
- In this activity, you revisited describing and analyzing situations involving exponential change, using graphs, tables, and equations, viewing them as functions and expressing them using function language and notation.
- 5.8.3: Self Check
- 5.8.3: Additional Resources
- 5.8.4: Function Notation
- In this activity, you considered a situation as a function of time in years, determined the meaning of a point in this context, and wrote an equation using function notation to represent the situation.
After these activities, you completed the following practice:
