 Function[Function f, Number a, Number b]
 Yields a function graph, that is equal to f on the interval [a, b] and not displayed outside of [a, b].
 Note: This command is deprecated. To restrict the function’s domain, create a conditional function using the If command, e.g.
f(x) = If[1 < x < 1, x²]
.  Note: This command does not work with Tools / Macros. Use the If command as above.
 Function[<List of Numbers>]
 Yields the following function: The first two numbers determine the start xvalue and the end xvalue. The rest of the numbers are the yvalues of the function in between in equal distances.
Example:
Function[{2, 4, 0, 1, 0, 1, 0}]
yields a triangular wave between x=2 and x=4.
Function[{3, 3, 0, 1, 2, 3, 4, 5}]
yields a linear equation with slope =1 between x=3 and x=3.
Following text is about a feature that is supported only in GeoGebra 5.0.
