4.4.6 Lesson Summary

In this lesson, you learned how 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 helped you reach those goals:

• 4.4.1: Using Function Notation in Tables of Values
  • In this activity, you made observations about tables of values that incorporated function notation.
• 4.4.2: Defining Functions by a Rule
  • In this activity, you matched equations that used function notation to their descriptions. You also compared output values when the same input was entered into different equations.
  • 4.4.2: Self Check
  • 4.4.2: Additional Resources
• 4.4.3: Using Tables to Find Function Rules
  • In this activity, you worked to find function rules for a table of values. You also determined the meaning of values given function notation in the context of the problem. You then sketched a graph of the function.

  • 4.4.3: Additional Resources
• 4.4.4: Writing a Rule Using Function Notation
  • In this activity, you wrote a rule from a table of values in function notation. You then used that rule to find other values of the function.

After these activities, you completed the following practice:
