Atenció, el denominador s'anul·la per a aquests valors, però només en un dels casos es tracta d'una discontinuïtat asimptòtica. <br />
Choice 3
Answer
té una discontinuïtat evitable en x = #a i una discontinuïtat asimptòtica en x=#c

Molt bé. El denominador s'anul·la per a aquests dos valors, però en <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mi»x«/mi»«mo»=«/mo»«mi»#a«/mi»«/math»</span> existeix el límit de la funció en aquest punt.
Choice 4
Answer
té una discontinuïtat de salt en x = #a i una discontinuïtat asimptòtica en x=#c

Atenció, el límit quan x tendeix a #a existeix (els límits laterals coincideixen), per tant, la discontinuïtat no és de salt. <br />
