Sea a>0, real, y definida como a) Encontrar TODOS los posibles valores de a que hacen que f tenga algún punto crítico. b) Elegir uno de los valores de ''a'' hallados y hacer un análisis de los puntos...(saben el resto ya de memoria, creo) c)Analizar la existencia de extremos absolutos
Espero que este ejercicio haya contribuído. Saludos, y suerte en el parcial.

la verdad no recuerdo si este lo hice o era uno muy parecido, pero tengan cuidado porque al tomar a = 4/5 si bien el discriminante se hace 0, el hessiano tambien, asique no vale el criterio. tal vez es mejor tomar a=1 que tambien es una cuenta sencilla y creo que para ese valor el hessiano es distinto de 0. igual se puede serolver de las 2 formas, y si te da que el hessiano vale 0 y no sabes como resolverlo de otra forma, tomas otro "a" y probas denuevo. Si me equivoque de ejercicio perdon, pero esta bueno ternerlo en cuenta.

Muy copado, en particular me puse a mirar la parte a), ya que lo demas son solo "cuentas"
