4.6.7 Lesson Summary

In this lesson, you learned how to:

• Identify important features of graphs of functions and explain what they mean in the situations represented.
• Explain and apply the terms “horizontal intercept,” “vertical intercept,” “maximum,” and “minimum” when talking about functions and their graphs.
• Identify important features of linear functions.

Here are the activities that helped you reach those goals:

• 4.6.1: Interpreting Statements in Function Notatio
  • In this activity, you interpreted function notation using a graph. You completed mathematical statements and found the value of variables by reading the information from a graph.
• 4.6.2: Analyzing Graphs of Functions
  • In this activity, you looked at the graphs of two different real-life functions. You identified key features such as minimum and maximum, $x$-intercepts and $y$-intercepts, and what they mean in a real-life situation.

  • 4.6.2: Additional Resources
• 4.6.3: Connecting Graphical and Verbal Representations of a Function
  • In this activity, you continued working with graphs, function notation, and real-life situations. You interpreted statements about a real-life graph and connected them to the function notation that represented them.

• 4.6.4: Key Features of Linear Functions
  • In this activity, you recognized the $x$-intercepts, zeros, slope, and $y$-intercepts of linear functions.

• 4.6.5: Interpreting Graphs
  • In this activity, you examined specific points and key features on the graph and interpreted their meaning verbally and algebraically.

After these activities, you completed the following practice:
