In this lesson, you learned how to:
- Graph a quadratic function given in vertex form, showing the maximum or minimum and the -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:
