The given graph is the graph of a polynomial function. Give the possible values for the degree of the polynomial, and give the sign ( + or - ) for the leading coefficient. X What is/are possible degree(s) of the polynomial? O A. The possible degrees of the polynomial are 7, 9, 11, etc. O B. The possible degrees of the polynomial are 8, 10, 12, etc. C. The possible degrees of the polynomial are 5, 6, or 7. O D. The possible degrees of the polynomial cannot be determined. The sign of the leading coefficient of the function is
