This is a lesson plan on using x = -b/2a to determine the axis of symmetry from a quadratic function and using the axis of symmetry to find the vertex.
There is also an example of using the axis of symmetry and vertex to graph the parabola (instead of using a table of values).
This lesson is for a double-period class but can be split into two days with additional examples and real-world problem solving as well.
The lesson plan includes an opening activity, minilesson with guided steps through the process, examples, class activities and a worksheet for home work. Answer keys included.
Common Core standards included on cover page for High School Algebra and High School Functions.
NOTE: You may need Equation Editor or MathType to make changes to some of the symbols.
