Answer

Vertical Asymptote: $x = 1$ Horizontal Asymptote: $y = -1$

Work Step by Step

The vertical asymptote travels vertically and crosses the x axis. The point at which it crosses the x axis denotes the asymptote. Therefore, looking at the graph, we see that the asymptote travelling vertically crosses the x axis at 1. Therefore, our vertical asymptote is x = 1. The horizontal asymptote travels horizontally and crosses the y axis. The point at which it crosses the y axis denotes the asymptote. Therefore, looking at the graph, we see that the asymptote travelling horizontally crosses the y axis at -1. Therefore, y = -1.
