Here is the graph: http://i.imgur.com/5a7wi.png

There is a removable discontinuity at x=-3 -- that is False because there is an open hole?

There is a removable discontinuity at x=-1 - is that false because there is an open hole and one closed?

There is a removable discontinuity at x=1 - Also false because one open and closed

Thank You for checking
