"Use a graphing calculator to sketch the following function. Find the value c where the function fails to exist, and graphically find the limit of f(x) as x approaches c from the left and the right.

f(x)= 3/(x-4)

Ok, so what I don't understand is how I can define a limit from the left and right when the function in unbounded. I know that at 4 c fails to exist, so isn't that the limit from both sides?
