About This Lesson
http://www.freemathvideos.com In this video series I show you how to graph a quadratic function by determining the vertex and axis of symmetry. Once we know the axis of symmetry and vertex we can use a table to find points to the left or right of the axis of symmetry and then use reflection to graph the other points. Once we have the graph we then determine the domain and range. We can also analyze the x and y intercepts as well as the number of solutions a given graph will have.
