<p><span style="font-weight: bold; color: #000080;"><span style="font-weight: bold;">Només pot ser discontínua en x = #a ja que quan s'anul·la el denominador de la segona funció, aquesta encara no està generant la imatge de la funció.</span></span></p> <p><span style="font-weight: bold; color: #000080;"><span style="font-weight: bold;">Si és contínua en x = #a, cal que els límits laterals de les dues funcions siguin iguals a la imatge de la funció.</span></span></p> <p><span style="font-weight: bold; color: #000080;"><span style="font-weight: bold;">En x = a, la funció que permet calcular la imatge és #f1</span></span></p> <p><span style="font-weight: bold; color: #000080;"><span style="font-weight: bold;">Aquesta imatge ha de ser igual al límit de l'altra funció (#f2) que només funciona per x>#a per tant el límit s'ha de calcular a #a+<br /></span></span></p> <p> </p> <p> </p>
