In this lesson, you learned how to:
- Recognize the "vertex form" of a quadratic equation.
- Relate the numbers in the vertex form of a quadratic equation to its graph.
Here are the activities that helped you reach those goals:
- 7.15.1: Analyzing Two Sets of Equations
- In this activity, you looked at equations in different forms and compared and contrasted them.
- 7.15.2: The Vertex Form
- In this activity, you explored the different forms from 7.15.1 and proved that the different forms, factored, standard, and vertex, are equivalent.
- 7.15.2: Self Check
- 7.15.2: Additional Resources
- 7.15.3: The Coordinates of the Vertex
- In this activity, you used graphing technology to explore how changing the numbers, or parameters, in the vertex form affected the graph of a quadratic.
- 7.15.3: Self Check
- 7.15.3: Additional Resources
- 7.15.4: The Graph of a Function in Vertex Form
- In this activity, you examined a quadratic function in vertex form and identified the vertex and if the graph of the function opens up or down.
After these activities, you completed the following practice:
- 7.15.5: Practice
