numpy.polyval(p, x) method evaluates a polynomial at specific values.
If ‘N’ is the length of polynomial ‘p’, then this function returns the value
p : [array_like or poly1D] polynomial coefficients are given in decreasing order of powers. If the second parameter (root) is set to True then array values are the roots of the polynomial equation.
For example : poly1d(3, 2, 6) = 3x2 + 2x + 6
x : [array_like or poly1D] A number, an array of numbers, for evaluating ‘p’.
Return:Evaluated value of polynomial.
