7.11.7 Lesson Summary

In this lesson, you learned how to:

• Graph a quadratic function given in factored form.
• Find the vertex and $y$-intercept of the graph of a quadratic function in factored form without graphing it first.

Here are the activities that helped you reach those goals:

• 7.11.1: Finding Coordinates
  • In this activity, you determined the missing values of coordinates given a function and a graph of a quadratic.
• 7.11.2: The Factored Form of a Quadratic Expression and the $x$-intercepts of Its Graph
  • In this activity, you were given a quadratic function in factored form. You used this function to complete a table and determine the $x$-intercepts and vertex of the graph of the function.
  • 7.11.2: Self Check
  • 7.11.2: Additional Resources
• 7.11.3: Sketching a Graph of a Quadratic Function Using at Least Three Identifiable Points
  • In this activity, you continued to determine the intercepts and vertex of a quadratic and used these points to graph the quadratic function.
  • 7.11.3: Self Check
  • 7.11.3: Additional Resources
• 7.11.4: Using the Vertex and Axis of Symmetry of Quadratics
  • In this activity, you determined the vertex and axis of symmetry of a quadratic and used these to graph the quadratic function.
  • 7.11.4: Self Check
  • 7.11.4: Additional Resources
• 7.11.5: Graphs of Quadratic Functions
  • In this activity, you once again identified specific points from a quadratic function and used them to graph the function.

After these activities, you completed the following practice:
