Determine if the graph can represent a polynomial function. If so$,$ assume the end behavior and all turning represented on the graph.

a$.$ Determine the minimum degree of the polynomial based on the number of turning points.

b$.$ Determine whether the leading coefficient is positive or negative based on the end behavior and whether the degre polynomial is odd or even.

c$.$ Approximate the real zeros of the function, and determine if their multiplicity is odd or even.
