plot(f, h, v, options)
vertical range (optional)
If either of the range endpoints of the horizontal range contains +-infinity, an infinity plot is generated.
An infinity plot is obtained by transforming -infinity .. infinity to −1..1 by a transformation that approximates arctan. This is a nice way of getting the entire picture of f(x) on the display. Such a graph, although distorted near x = -infinity and infinity, contains a lot of information about the features of f(x).
Because the view is already determined for infinity plots, the view option has no effect.
The command to create the plot from the Plotting Guide is
