In this lesson, you will continue to develop your ability to interpret statements in function notation in terms of a situation, including reasoning about inequalities.

When you finish this lesson, you will be able 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 will help you reach those goals:

• 4.3.1: Comparing Function Values
• 4.3.2: Writing Statements from Function Notation
  • 4.3.2: Self Check
  • 4.3.2: Additional Resources
• 4.3.3: Comparing Statements in Function Notation
  • 4.3.3: Self Check
  • 4.3.3: Additional Resources
• 4.3.4: Using Function Notation with a Real-World Example

After that, you’ll practice and review.

• 4.3.5: Practice
• 4.3.6: Lesson Summary
