What are the points of discontinuity? y=((x-3))/(x^2-12x+27)
a. x=4,x=9,x=1
b. x=-9,x=-3
c. x=-9,x=-3,x=-1
d. x=9,x=3

Option D - x=9,x=3

Step-by-step explanation:

Given :

To find : What are the points of discontinuity?

Solution :

To determine the points of discontinuity we have to place denominator equal to zero.

So, The points of discontinuity is at x=9 and x=3.

Therefore, Option D is correct.

huh? im pretty sure it is in 199
