In this lesson, you will use function notation to describe the rule of a function or how a function behaves at any value of input. In addition, you will represent situations symbolically to solve problems.

When you finish this lesson, you will be able to:

• Explain rules of functions when they are written in function notation and create tables and graphs to represent the functions.
• Write equations that represent the rules of functions.

Here are the activities that will help you reach those goals:

• 4.4.1: Using Function Notation in Tables of Values
• 4.4.2: Defining Functions by a Rule
  • 4.4.2: Self Check
  • 4.4.2: Additional Resources
• 4.4.3: Using Tables to Find Function Rules
  • 4.4.3: Self Check
  • 4.4.3: Additional Resources
• 4.4.4: Writing a Rule Using Function Notation

After that, you’ll practice and review.

• 4.4.5: Practice
• 4.4.6: Lesson Summary
