I tried to graph (using a graphical calculator) few equations that I know that they have holes or vertical segments. Like:
(x^2-5)/(x-2) and (x^2-4)/(x-2)
However, the calculator does not give an accurate graph. So I tried Mathematica to graph using the Plot function but, unfortunately, it gave me the same graph. So, is there another way to graph it explicity? showing all the holes and the vertical segments? I'll appreciate if someone can help me.
Thanks in advance.
