Function[ <Function>, <Start x-Value>, <End x-Value> ]
Yields a function graph, that is equal to the given function on the interval [Start x-Value, End x-Value] and not displayed outside of [Start x-Value, End x-Value].
Example: Function[x^2, -1, 1] yields the function graph of x^2 in the interval [-1, 1].
Note: This command is deprecated. To restrict the function’s domain, create a conditional function using the If command.
Example: f(x) = If[-1 < x < 1, x²].
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.
