Explore Graphs and Factors
Activity Overview
Students use a graphing calculator to explore the relationship between the linear factors of a quadratic function and its zeros. They learn that the x-intercepts and axis of symmetry of a quadratic function can be determined from its linear factors.
This Technology Lab accompanies Lesson 5-3 from the ©2007 Holt, Rinehart and Winston Algebra 2 textbook.
Before the Activity
- Review the lesson PDF files.
- Make copies of the lesson PDF files for your class.
During the Activity
Students will:
- Graph linear and quadratic functions.
- Identify x-intercepts.
- Explore the relationship between the linear factors of a quadratic function and its zeros.
- Learn that the x-intercepts and axis of symmetry of a quadratic function can be determined from its linear factors.
