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$$\frac{\left(15625 \left(100 x - 731\right)^{2} - 697971125000 + \frac{1395942250 \left(100 x - 731\right)}{x} + \frac{342963238698971}{x^{2}}\right) e^{- \frac{625 \left(x - \frac{731}{100}\right)^{2}}{5583769}}}{3117847624536100 \sqrt[10]{x}} = 0$$

Además hay que calcular los límites de y'' para los argumentos tendientes a los puntos de indeterminación de la función:
Puntos donde hay indeterminación:
$$x_{1} = 0$$
$$\lim_{x \to 0^-}\left(\frac{\left(15625 \left(100 x - 731\right)^{2} - 697971125000 + \frac{1395942250 \left(100 x - 731\right)}{x} + \frac{342963238698971}{x^{2}}\right) e^{- \frac{625 \left(x - \frac{731}{100}\right)^{2}}{5583769}}}{3117847624536100 \sqrt[10]{x}}\right) = - \infty \left(-1\right)^{\frac{9}{10}}$$
$$\lim_{x \to 0^+}\left(\frac{\left(15625 \left(100 x - 731\right)^{2} - 697971125000 + \frac{1395942250 \left(100 x - 731\right)}{x} + \frac{342963238698971}{x^{2}}\right) e^{- \frac{625 \left(x - \frac{731}{100}\right)^{2}}{5583769}}}{3117847624536100 \sqrt[10]{x}}\right) = \infty$$
- los límites no son iguales, signo
$$x_{1} = 0$$
- es el punto de flexión
