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$$- 2^{3 - \left|{x}\right|} \log{\left(2 \right)} \operatorname{sign}{\left(x \right)} \operatorname{sign}{\left(\left(\frac{1}{2}\right)^{\left|{x}\right| - 3} - 4 \right)} = 0$$
