#### Function Input

To the left of the graph area you will find a text box in which you can type in
your function. There is no limit of the number of functions you can add on a single
graph. After the a function is added you may hide it, delete and edit it. The grapher
supports single variable functions. Use 'x' as the variable of the function.
