4.3.6 Lesson Summary

In this lesson, you learned how to:

• Describe the connections between a statement in function notation and the graph of the function.
• Use function notation to efficiently represent a relationship between two quantities in a situation.
• Use statements in function notation to sketch a graph of a function.

Here are the activities that helped you reach those goals:

• 4.3.1: Comparing Function Values
  • In this activity, you compared function values given function notation and a graph.
• 4.3.2: Writing Statements from Function Notation
  • In this activity, you interpreted the meaning of function notation in a given situation and wrote a statement describing the situation.
  • 4.3.2: Self Check
  • 4.3.2: Additional Resources
• 4.3.3: Comparing Statements in Function Notation
  • In this activity, you interpreted equations and inequalities involving function notation to compare which values were equal, larger, or smaller.
  • 4.3.3: Self Check
  • 4.3.3: Additional Resources
• 4.3.4: Using Function Notation with a Real-World Example
  • In this activity, you looked at a real-world example of function notation where time was the input and the number of visitors to a website was the output.

After these activities, you completed the following practice:
