Find the vertical and horizontal asymptotes for the graph of
The vertical asymptotes are found at the "bad" points, i.e. the points, which are not the domain. In this case, we have one "bad" point, where the denominator equals zero: x=2. We have
and
So x=2 is a vertical asymptote. On the other hand, we have
and
So y=1 and y= -1 are horizontal asymptotes.
