Find the intersection points of a polynomial, given by its vector of coefficients with the X-axis and the Y-axis.
Input: a polynomial represented by a vector of coefficients p .
The function returns a vector x containing the points of intersection of the polynomial with the X-axis,
where x is sorted in ascending order and rounded to 4 digits after the decimal point.
In addition, the function returns the point of intersection of the polynomial with the Y-axis in the variable y .
Hint: use the polynomial functions of MATLAB.
Example: for the polynomial p(x) = x^2 - 3x + 1.25
given by its vector of coefficients  p = [1  -3  1.25]
x = [ 0.5 
       2.5 ]
y = 1.25
* It can be assumed that the polynomials of the tests have real values ​​at the points of intersection with the x-axis.
