4.2.6 Lesson Summary

4.2.6 • Lesson Summary

In this lesson, you learned how to:

  • Use function notation to express functions that have specific inputs and outputs.
  • Explain what function notation is and why it exists.
  • Explain a statement written in function notation in terms of a situation.

Here are the activities that helped you reach those goals:

  • 4.2.1: Interpreting Graphs to Answer Questions
    • In this activity, you used graphs to answer questions and also interpreted points on graphs to answer questions.
  • 4.2.2: Interpreting Statements Written in Function Notation
    • In this activity, you used function notation to represent different situations. You identified the inputs for the functions as they changed.
    • 4.2.2: Self Check
    • 4.2.2: Additional Resources
  • 4.2.3: Finding a Unique Output for Each Input
    • In this activity, you identified inputs and outputs given rules. You determined if the inputs and outputs created a function.
    • 4.2.3: Self Check
    • 4.2.3: Additional Resources
  • 4.2.4: Understanding Function Notation Using Application Problems
    • In this activity, you read function notation in terms of the situation. You also wrote function notation to represent the given situation.

After these activities, you completed the following practice:

  • 4.2.5: Practice
