Asymptotes will occur where you have a denominator equal to 0. So the first one is obvious: when x = -2, you'll get one, so the equation of that asymptote is x = -2. Just rearrange the equation to get x in terms of f(x) and then you'll see the value of f(x) that produces the asympote. This equation will be y = f(a) where a is the x co-ordinate.
