Determine if the graph can represent a polynomial function. If so, assume that the end behavior and all turning points are represented in the graph.
(a) If the graph is a polynomial, determine the minimum degree of the polynomial.
(b) If the graph is a polynomial, determine whether the leading coefficient is positive or negative based on the end behavior and
whether the degree of the polynomial is odd or even.
(c) If the graph is a polynomial, approximate the real zeros of the function, and determine if their multiplicities are even or odd.
