Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
Ejemplo de respuesta: si la respuesta es −7x5+7x3−8x, digite $-7x^5+7x^3-8x en la barra de respuesta.
f(x)={{a}x3+{b}x2+{c}x+{d}}
f′(x)=
f″(x)=
Resolver la ecuación f′(x)=0, para determinar los valores de x buscados:
Valor de x donde hay un máximo =
Valor de x donde hay un mínimo =
