To use this PowerPoint presentation you should have GeoGebra installed on your local computer.  Click here for GeoGebra installer downloads.

It is also recommended that you use Firefox or Chrome for your default browser when using this PowerPoint.  When you click the hyperlinks in the PowerPoint presentation, you will then be given an option of open or save.  It appears that Internet Explorer will treat the .ggb files as a .zip file and will only unpack them.  I don't know how other browsers will handle these links.

Link to PowerPoint presentation "Graphical Solutions of the General Cubic Function."  We show the steps needed to find the non-real zeros of a cubic polynomial function which has only one real zero.  We use only the graph of the polynomial.  Within the PowerPoint slides are links to GeoGebra files which give examples of graphical solving techniques for quadratic and cubic functions.

Here is a link to the quadratic function 2D graph illustrator.
