El gráfico cruce el eje Y cuando x es igual a 0:
sustituimos x = 0 en -(cos((3*x^5 - 10*x + 10^(1/3) - 2 - 10*sqrt(2))/10) + atan((10*x^5 - 10*sqrt(5)*x^4 + 10*x^3 + 3*x^2 - 3*sqrt(5)*x + 1)/(2*x^2 - 2*sqrt(5)*x + 2))).
$$- (\cos{\left(\frac{- 10 \sqrt{2} + \left(-2 + \left(\left(3 \cdot 0^{5} - 0\right) + \sqrt[3]{10}\right)\right)}{10} \right)} + \operatorname{atan}{\left(\frac{\left(\left(\left(\left(10 \cdot 0^{5} - 0^{4} \cdot 10 \sqrt{5}\right) + 10 \cdot 0^{3}\right) + 3 \cdot 0^{2}\right) - 0 \cdot 3 \sqrt{5}\right) + 1}{\left(2 \cdot 0^{2} - 0 \cdot 2 \sqrt{5}\right) + 2} \right)})$$
Resultado:
$$f{\left(0 \right)} = - \operatorname{atan}{\left(\frac{1}{2} \right)} - \cos{\left(- \frac{\sqrt[3]{10}}{10} + \frac{1}{5} + \sqrt{2} \right)}$$
Punto:
(0, -atan(1/2) - cos(1/5 + sqrt(2) - 10^(1/3)/10))
