for vertical asymptote, let the denominator equal to zero, then solve for x
 
for horizontal asymptote,
see the end behavior of f(x) as x approaches +/- infinite

and continuous fnct, jump discont., removable discont.(where the discontinuity can be removed by factoring)
 
critera for continuity,
f(a) exist,
lim as x approaches a exist,
f(a)=limf(x)
