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:
$$\left|{\left(- \frac{3 \operatorname{sinc}^{2}{\left(\frac{3 \left(x - \frac{7}{2}\right)}{2} \right)}}{4} - \frac{3 \operatorname{sinc}^{2}{\left(\frac{3 \left(x + \frac{7}{2}\right)}{2} \right)}}{4}\right) + \operatorname{sinc}^{2}{\left(\frac{3 \left(x - 3\right)}{2} \right)}}\right| = 0$$

Paridad e imparidad de la función
Comprobemos si la función es par o impar mediante las relaciones f = f(-x) и f = -f(-x).
Pues, comprobamos:
$$\left|{\left(- \frac{3 \operatorname{sinc}^{2}{\left(\frac{3 \left(x - \frac{7}{2}\right)}{2} \right)}}{4} - \frac{3 \operatorname{sinc}^{2}{\left(\frac{3 \left(x + \frac{7}{2}\right)}{2} \right)}}{4}\right) + \operatorname{sinc}^{2}{\left(\frac{3 \left(x - 3\right)}{2} \right)}}\right| = \left|{\frac{3 \operatorname{sinc}^{2}{\left(\frac{3 x}{2} - \frac{21}{4} \right)}}{4} - \operatorname{sinc}^{2}{\left(\frac{3 x}{2} + \frac{9}{2} \right)} + \frac{3 \operatorname{sinc}^{2}{\left(\frac{3 x}{2} + \frac{21}{4} \right)}}{4}}\right|$$
- No
