Question 708492
Describe the vertical asymptote(s) and hole(s) for the graph of 
y =x-5/x^2+4x+3.
To find vertical asymptotes, set denominator=0, then solve for x values that make the function undefined.
x^2+4x+3=0
(x+3)(x+1)=0
x=-3
or
x=-1
asymptotes: x=-3 and x=-1
There are no holes in the graph
ans: a
