Could anyone show me what the graph of y=(x+1)/(x1) looks like?

This should help:
[tex]y=\frac{x+1}{x1}[/tex] [tex]=\frac{(x1)+2}{x1}[/tex] [tex]=\frac{x1}{x1}+\frac{2}{x1}[/tex] [tex]=1+\frac{2}{x1}[/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?

How would simplify y=(1+2x)/(1x)
