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 
.
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.
. Please present the output rounded to 4 decimal places and sorted ascending.--------------
