Algebra 19.9.6 Lesson Summary

Search for key terms or text.

In this lesson, you learned how to:

  • Identify the vertex of a quadratic function from an equation.
  • Write quadratics in vertex, factored, and standard forms.
  • Write quadratic functions in vertex form given a vertex and another point.

Here are the activities that helped you reach those goals:

  • 9.9.1: Finding the Vertex in Vertex Form
    • In this activity, you identified the vertex from the quadratic function that was written in vertex form.
  • 9.9.2: Different Forms of Quadratics
    • In this activity, you practiced writing quadratic functions in the different forms: vertex form, factored form, and standard form.
    • 9.9.2: Self Check
    • 9.9.2: Additional Resources
  • 9.9.3: Vertex Form Given a Vertex and Point
    • In this activity, you continued working with quadratic functions and their forms by writing a quadratic function in vertex form given its vertex and a point on the quadratic graph.
    • 9.9.3: Self Check
    • 9.9.3: Additional Resources
  • 9.9.4: Rewriting Quadratics
    • In this activity, you wrote the equation for a quadratic function in vertex form when given a transformation of the parent function.

After these activities, you completed the following practice:

  • 9.9.5: Practice
