Obje For Exercises 45-52, 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. 45. y 46. y 47. y 4 3 3 3 2 1 -5-4-3-2-1 123 4 -2-1 1 23 45 4-3-2-1 23 4 5 48. 5 4 3 2 375 1 234
