Ejemplo de respuesta: si la respuesta es
$-7x^5+7x^3-8x$, digite $-7x^5+7x^3-8x en la barra de respuesta.
$f(x)=\\simplify[all,!collectNumbers,!noleadingminus]{{a}x^3+{b}x^2+{c}x+{d}}$
\n$f'(x)=$ [[2]]
\n$f''(x)=$ [[3]]
\n\nResolver la ecuación $f'(x)=0$, para determinar los valores de $x$ buscados:
\nValor de $x$ donde hay un máximo $=$ [[0]]
\nValor de $x$ donde hay un mínimo $=$ [[1]]
