Plotting Asymptotes in Mathematica
Hi.
I'm just starting to learn how to use Mathematica, and I can't work out how to plot a graph, such as $y=\frac{a}{x-b}+c$, without it showing the vertical asymptote.

I would also like to know if there's a way to show the horizontal asymptote on the graph.

Thanks for your help

Found out how to do it.

If anyone's interested, apparently you need to plot the horizontal asymptotes, and to get rid of the vertical asymptote you can
use $Exclusions\rightarrow (x,b)$
Though this does also obviously exclude any other value which may be on the line (e.g. in a manipulatable graph)
