Answer:

Vertical: #x=0uarr and uarrx=-2darr#. Horizontal:#larry=0rarr#.
For visual effect, see the graph.

Explanation:

#yto oo#, as #x to 0. yto +_oo#, as #x to -2#.

The line y=0, besides making x-intercepts #+-1/sqrt2#, is asymptotic

to two ( of the three ) branches of the graph, in the two opposite directions.
