Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d x} f{\left(x \right)} = $$
primera derivada$$\frac{3 x^{2} \log{\left(x \right)}}{\left(1 - x^{3}\right)^{2}} + \frac{1}{x \left(1 - x^{3}\right)} = 0$$
