Function[ <Function>, <Start x-Value>, <End x-Value> ]
Note:
This command is deprecated.
To restrict a function’s domain, instead use the If command:
Example: f(x) = If[-1 <= x <= 1, x^2].
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.
Note: This command does not work with Tools / Macros. Use the If command as above.
