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:

• 5.8.5: Practice
• 5.8.6: Lesson Summary
