 Graph . What is the domain (expressed in interval notation)? Does a hole exist in the graph? If so, then what are the coordinates of the hole? You must show all work to receive full credit; this includes clearly defining the graph and showing it's coordinates.  The x-values cannot include -2, -1, 1, 3, and 5.
