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:
$$\left(- x - 1\right) \sin{\left(\frac{\sqrt{2} x}{2} \right)} + \left(\left(- x - 1\right) \cos{\left(\frac{\sqrt{2} x}{2} \right)} - 1\right) = 0$$

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = 0$$
(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:
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = $$
segunda derivada
$$\frac{\left(x + 1\right) \sin{\left(\frac{\sqrt{2} x}{2} \right)}}{2} + \frac{\left(x + 1\right) \cos{\left(\frac{\sqrt{2} x}{2} \right)}}{2} + \sqrt{2} \sin{\left(\frac{\sqrt{2} x}{2} \right)} - \sqrt{2} \cos{\left(\frac{\sqrt{2} x}{2} \right)} = 0$$
