<PRE><B>Question 13422</B>
Notice that this factors into:{{{ ((x+4)(x+2))/((x-2)(x+1)) }}}.


Consequently, there are roots at x= -4 and x=-2, and there are asymptotes at x= 2, and x=-1, since the function is UNDEFINED at x = 2 and x=-1.  It may look as if the graph touches or crosses these asymptotes, but rest assured--IT DOES NOT!!


{{{ graph (300, 300, -5, 5, -10, 10, (x^2+6x+8)/(x^2-x-2))}}}
