Suppose that you want to write a program that inputs customer data including name, zipcode, balance, and regionnum. at the end of the program, a summary of the number of customers in each of 12 sales regions who owe more than $1000 each is displayed. the most likely statement during the main processing loop would be
a. customercount[balance] = customercount[balance] + 1
b. customercount[regionnum] = customercount[regionnum] +1
c. customercount[regionnum] = regionnum - 1
d. customercount[balance] = balance + customercount[regionnum]

Function name: poly parameters: int returns: int description: a polynomial of degree n with coefficients a0,a1,a2,a3, . . ,an is the function p(x) = a0+a1x+a2x2+a3 ∗ x3+ . . +an ∗ xn this function can be evaluated at different values of x. for example, if: p(x) = 1+2x+ x2, then p(2) = 1+2 ∗ 2+22 = 9. if p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . , an of a polynomial p(x) and a value x. the function will return poly(x), which is the value of the polynomial when evaluated at x.
