El gráfico de la función cruce el eje X con f = 0
o sea hay que resolver la ecuación:
$$\frac{\left(4^{x} - 3\right) \log{\left(\frac{417}{100} - 2^{x} \right)} \tan{\left(\frac{x}{2} \right)}}{- \frac{1}{2} + \frac{\log{\left(16 \right)}}{\log{\left(x \right)}}} = 0$$
Resolvermos esta ecuaciónPuntos de cruce con el eje X:
Solución analítica$$x_{1} = \frac{\log{\left(3 \right)}}{2 \log{\left(2 \right)}}$$
$$x_{2} = \log{\left(\left(\frac{317}{100}\right)^{\frac{1}{\log{\left(2 \right)}}} \right)}$$
