Apolynomial of degree n with coefficients a0, a1, a2, an is the function p(x) = a0 + a1x + a2x 2 + a3 ∗ x 3 + + an ∗ x n this function can be evaluated at different values of x. for example, if p(x) = 1 + 2x+ x 2, then p(2) = 1 + 2 ∗ 2 + 22 = 9. if p(x) = 1 + x 2 + x 4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, an of a polynomial p(x) and a value x. the function will return p(x), which is the value of the polynomial when evaluated at x. note that the usage below is for the three examples shown. > > > poly([1, 2, 1], 2) 9 > > > poly([1, 0, 1, 0, 1], 2) 21 > > > poly([1, 0, 1, 0, 1], 3) 91
