Question 1101725
<pre>
Non-removable discontinuity for it approaches infinity for there is
an asymptote at x=3.

[Note: If it had been F(x) = (x^(2)-9)/(x-3), there would have been a
removable discontinuity at x=3, for then the numerator would have 
factored and had a factor of x-3, which is the denominator.]
