Algebra 17.15.6 Lesson Summary

Search for key terms or text.

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
