Question 1064351: State excluded values
x^2-11x+24/x-8
9n+9/n^2-n-2
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! The first one cannot have x=8, because the denominator would be 0.
The function is (x-8)(x-3)/(x-8), which is x-3 after simplification. There would be a hole in the graph at x=8, where the function is 0/0.
------------------
This denominator factors into (n-2)(n+1)
n cannot equal 2 or -1.
9(n+1)/(n-2)(n+1)=9/(n-2). There would be a hole in the graph at n= -1 and a vertical asymptote at n=2.
