7)
x - 6 x - 6
___________ = __________
x^2 + 5x + 6 (x + 2) ( x + 3)
We have no "holes" (one of the factors would have to cancel for this to happen )....the vertical asymptotes are at x = -3 and x = -2
8) We have a same degree / same degree situation....thus....the horizontal asymptote will be the ratio of the lead coefficients in each polynomial = -3/9 = -1/3
