## MathJax

MathJax is an Open Source, JavaScript utility to display mathematics in web pages. With very simple configuration and LaTeX or MathML, we can easily display typeset mathematics on web pages. You can read more about MathJax at http://www.mathjax.org.

Here is an example of MathJax in action:

When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are $x = \frac {-b \pm \sqrt{b^2-4ac} } {2a}.$

## JSXGraph

JSXGraph is another Open Source, Javascript utility for displaying mathematics on web pages. With JSXGraph, you can build interactive 2-D graphics for online demonstrations and discovery exercises. You can read more about JSXGraph and see several examples at http://jsxgraph.uni-bayreuth.de/wp/.

Here is an example of JSXGraph in action.

### Investigating Domain and Range of a Piecewise Function

This demo investigates the domain and range of a piecewise function. The function to be investigated is on the left. When the Animate On/Off toggle is selected, the domain is plotted in the first graph in the second column. The range is plotted in the second graph in the second column. There is also a slider that you can use to generate the domain and range graphs.

Both MathJax and JSXGraph are mobile-device (iOS, Android) and browser independent. They just work!
