Inflection points are points along the graph curve of a function, where the curvature of the curve changes from concave to convex, or vice versa. Consider the following the following binomial product function:

where the coefficient are given by the vector, . Write a function that outputs an array of the x-coordinates all of the inflections of .

For example, if :

The plot of the function shows 2 inflection points:

Therefore, the function output in this case should be: . Please present the output rounded to 4 decimal places and sorted ascending.
