Could anyone show me what the graph of y=(x+1)/(x-1) looks like?

[tex]y=\frac{x+1}{x-1}[/tex]

[tex]=\frac{(x-1)+2}{x-1}[/tex]

[tex]=\frac{x-1}{x-1}+\frac{2}{x-1}[/tex]

[tex]=1+\frac{2}{x-1}[/tex]

So it is the graph of y=1/x, just multiplied by two, shifted up by one, and shifted to the left by one.

Where does the +2 come from?
