Gráfico de la función
Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$y_{1} = 0$$
$$y_{1} = 0$$
Puntos de cruce con el eje de coordenadas X
El gráfico de la función cruce el eje Y con f = 0
o sea hay que resolver la ecuación:
$$\frac{\sin{\left(y \right)}}{y^{3}} = 0$$

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
$$\frac{d^{2}}{d y^{2}} f{\left(y \right)} = 0$$
(la segunda derivada es igual a cero),
las raíces de la ecuación obtenida serán los puntos de flexión para el gráfico de la función indicado:
$$\frac{d^{2}}{d y^{2}} f{\left(y \right)} = $$
segunda derivada
$$\frac{- \sin{\left(y \right)} - \frac{6 \cos{\left(y \right)}}{y} + \frac{12 \sin{\left(y \right)}}{y^{2}}}{y^{3}} = 0$$
