Product Description
Quadratic Grapher MS Excel Spreadsheet graphs up to 2 quadratic equations / functions at a time. It is color coded so it is easy to see which parabola corresponds to which equation.

It also displays 10 points. The x values can be changed to your liking.

It also finds the points of intersection between the two parabolas. This is useful for solving a system of two quadratic equations. It could probably even solve a system of two equations that has one quadratic and linear equation. Just input a=0 for the linear equation.

Amazingly, I was able to create an application within the spreadsheet that can find the quadratic function that passes through 3 given points. Just type in the 3 points and the spreadsheet can find the quadratic equation (parabola) that passes through those 3 points. Any 3 points will do!

It can also find the quadratic function given the vertex and one other point.

This spreadsheet was somewhat incomplete in that I haven't finished typing up the notes on it and I'm not sure that I have it set up to print very well.

The fields highlighted green are for user input. All other fields should be left alone. They should be password protected, but I'm not sure if they are since I didn't quite finish with it.

I will post a message here if and when the spreadsheet is updated.

I hope you and your students appreciate this product.
