In this lesson, you learned how to:

• Graph a quadratic function given in vertex form, showing the maximum or minimum and the $y$-intercepts.
• Find the maximum or the minimum of a quadratic function given in vertex form without first graphing it.

Here are the activities that helped you reach those goals:

• 7.16.1: Three Forms of Quadratic Expressions
  • In this activity, you identified which forms of quadratics would be best to use to find different characteristics of the graphs of the functions.
• 7.16.2: Graph Functions in Vertex Form
  • In this activity, you completed the graphs of quadratic functions using knowledge of finding the vertex from vertex form and the symmetry of parabolas.
  • 7.16.2: Self Check
  • 7.16.2: Additional Resources
• 7.16.3: Quadratic Equations and Graphs
  • In this activity, you matched graphs of quadratic functions with the appropriate equations in vertex form.
  • 7.16.3: Self Check
  • 7.16.3: Additional Resources
• 7.16.4: Sketching A Graph of an Equation
  • In this activity, you sketched the graph of a quadratic function using the vertex form. You graphed the vertex and two other points to complete the graph.

After these activities, you completed the following practice:
