For the function f whose graph is given, state the following. (If the limit is infinite, enter '∞' or '-∞', as appropriate. If the limit does not otherwise exist, enter DNE.) \text { (a) } \lim _{x \rightarrow \infty} f(x) \text { (b) } \lim _{x \rightarrow-\infty} f(x) \text { (c) } \lim _{x \rightarrow 1} f(x) \text { (d) } \lim _{x \rightarrow 3} f(x) (e) the equations of the asymptotes (Enter your answers as comma-separated lists.)
