Graphing Quadratic functions in Vertex form.

If you are currently teaching this section as we are in Menominee, then you are really going to like this tool.  This is a great way to show students how the different variables effect the graph of quadratics when using the vertex format. 

 

y = a( x - h )2 + k

 

Below is a link to this little tool. My kids thought this was really cool.

Great tool. We're coming up on this section also. The interactive site will come in handy. Thanks

I have seen this before.  I'd like to have the right class back now so I can use it!  Thanks for sharing.
