Can someone please tell me how to make this determination?
is the function con @ x=3
is the function con @ x=0
is the function con @ x=-4
Try to see what the value of the function is on each side of the test point. For instance, on the 3 point, test it at 2.9 and at 3.1 thence closer. Is the function approaching the same point?
Graphing it on your calculator may be easier.
