6. Find any points of discontinuity for the rational function.

y = x-8/x^2 +6x-7 (1 point)

x = 1, x = 7
x = 8
x = 1, x = –7
x = –1, x = 7

7. Describe the vertical asymptote(s) and hole(s) for the graph of y = x-5/x^2 +4x +3

asymptotes: x = –3, –1 and no holes.
asymptote: x = –3 and hole: x = –5
asymptotes: x = –3, –1 and hole: x = –5
asymptote: x = –5 and hole: x = –3

8. Find the horizontal asymptote of the graph of y = -4x^6 +6x +3/8x^6 +9x+3 (1 point)

y = 1
y = –1/2
y = 0
There is no horizontal asymptote.

6: 
If the denominator is 0 you have a discontinuity.
If you factor the denominator, it becomes: (x+7)(x-1).
This should give you a hint...
