Gráfico de la función
Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$x_{1} = 0$$
$$x_{1} = 0$$
Puntos de cruce con el eje de coordenadas X
El gráfico de la función cruce el eje X con f = 0
o sea hay que resolver la ecuación:
$$\frac{\left(- \sin{\left(x \right)} - \frac{2 \cos{\left(x \right)}}{x}\right) + \frac{2 \sin{\left(x \right)}}{x^{2}}}{x} = 0$$

Extremos de la función
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
$$\frac{- \cos{\left(x \right)} + \frac{2 \sin{\left(x \right)}}{x} + \frac{4 \cos{\left(x \right)}}{x^{2}} - \frac{4 \sin{\left(x \right)}}{x^{3}}}{x} - \frac{\left(- \sin{\left(x \right)} - \frac{2 \cos{\left(x \right)}}{x}\right) + \frac{2 \sin{\left(x \right)}}{x^{2}}}{x^{2}} = 0$$
