In this lesson, you will evaluate expressions at certain $x$-values to see if they produce an output of $0$. You will learn what the factored form can tell us about the vertex and the $y$-intercept of a graph representing a quadratic function.

When you finish this lesson, you will be able 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 will help you reach those goals:

• 7.11.1: Finding Coordinates
• 7.11.2: The Factored Form of a Quadratic Expression and the $X$-Intercepts of Its Graph
  • 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
  • 7.11.3: Self Check
  • 7.11.3: Additional Resources
• 7.11.4: Using the Vertex and Axis of Symmetry of Quadratics
  • 7.11.4: Self Check
  • 7.11.4: Additional Resources
