The points of intersection with the X-axis coordinate
Graph of the function intersects the axis X at f = 0
so we need to solve the equation:
$$\left( \sqrt[5]{- x x + 4} \left(\left(\sqrt{\cos{\left(x \right)}} \cos{\left(75 x \right)} + \sqrt{\left|{x}\right|}\right) - \frac{7}{10}\right), \ \sqrt{9 - x^{2}}, \ - \sqrt{9 - x^{2}}, \ - x\right) = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X
so we need to solve the equation:
$$\left( \sqrt[5]{- x x + 4} \left(\left(\sqrt{\cos{\left(x \right)}} \cos{\left(75 x \right)} + \sqrt{\left|{x}\right|}\right) - \frac{7}{10}\right), \ \sqrt{9 - x^{2}}, \ - \sqrt{9 - x^{2}}, \ - x\right) = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X
Extrema of the function
