If used effectively, I think that this site is a really good tool for students who are at least taking an intermediate algebra class and higher math. I spent 45 minutes reviewing the materials, playing with the graph function tools and found it simple and easy to use. Content quality is good; the site offers concepts that are educationally significant because you get instant results. Students and teachers will benefit by the ease-of-use and visual concepts of graphs. Lastly, first-time users will find this a fun and simple way to understand graphs and how they are used.

The material here provides important concepts in math. It does not appear to be
very difficult to teach or learn. It teaches material that will be needed in
future math classes. The site has effective graphics and multimedia. The
feedback is immediate.

Function Grapher is very easy to use. Although it may be too simple for
graphing more complicated equations, it works extremely well for its intentions.
Function Grapher is an excellent tool for someone who may not be able to
afford a graphing calculator or just needs a quick and simple graph. It is also
useful if a student wants to print out a graph to include in an assignment or a
paper.
