Below is the graph of a polynomial function with real coefficients. All local extrema of the function are shown in the graph. Use the graph to answer the following questions.

(a) Over which intervals is the function decreasing? Choose all that apply. (-00, -9) 0 (-9, -7) 0 (-3, 1) 0 (-3, 4) 0 (4, 6) 0 (6, 00) (b) At which x-values does the function have local minima? If there is more than one value, separate them with commas. (c) What is the sign of the function's leading coefficient? (Choose one) (d) Which of the following is a possibility for the degree of the function? Choose all that apply. 04 05 0 6 07 0 8 09
