##### Function

This article is about GeoGebra command.

##### Command Categories (All commands)

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 x-value and the end x-value. The rest of the numbers are the y-values 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.
