In this lesson, you will evaluate expressions at certain -values to see if they produce an output of . You will learn what the factored form can tell us about the vertex and the -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 -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:
