Find any points of discontinuity for the rational function.

1. (x + 6)(x + 2)(x + 8)

y = _____________________

(x + 9)(x + 7)

2. x - 8

y = _____________________

x^2 + 6x - 7

The first function is discontinuous when x = -9 and when x = -7

The second is discontinuous when x = -7 and when x = 1

There are no "points" of discontinuity, the curves approach an asymptote, not points.
