How to make true parabolas in Adobe Illustrator

Today, a post of technology and activities.

A Google search for making a parabola brought me to a nice quick article on making a parabola-looking curved line on eHow.com, but for a quick half-day project I am needing to draw a perfect and scalable vector.

Attached is a simple script to run in Adobe Illustrator that was hand-typed to build what is needed for my project.  Some convenient Javascript prompts are included to make it easy to use.

In illustrator, press Ctrl+F12 on Windows or Cmd+F12 on Mac or click File > Scripts > Other script and load the file, then read and follow the prompts.

Here are two parabolas made with this script:

Parabola of x = -0.3 through x = 0.3

Parabola of x = -3 through x = 3
