Module 3: Quadratic Functions
Add the quadratic function in vertex form to your copy of Formula Sheet. You will likely want to include a description of how a, p, and q affect the quadratic function.
Resave Formula Sheet in your course folder.
If you feel you have a solid understanding of how the shape and position of the parabola is influenced by the values of a, p, and q, go to Connect. Otherwise, complete Self-Check 2.
Self-Check 2
If you feel you need a bit more practice, complete questions 1 and 2 on page 157 of the textbook. Check your work in the back of the textbook. If you are still unclear about how to answer some questions, make sure you contact your teacher.
In future lessons make sure you use the quadratic function in the vertex form when deciding the position of the vertex. You will encounter other versions of the quadratic function that do not allow you to translate the numbers into vertex positions and orientations like the vertex form does.
