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$)$ Determine the minimum degree of the polynomial.

$($b$)$ 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$)$ Approximate the real zeros of the function, and determine if their multiplicities are even or odd.

Part: $0/5$

$($a$)$ Determine the minimum degree of the polynomial.
