Use the graph to answer the following questions. (a) Over which intervals is the function increasing? Choose all that apply. O (-00, -9) 0 (-9, -7) 0 (-3, 1) 0 (4, 7) 0 (1, 7) 0 (7, 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? undefined (d) Which of the following is a possibility for the degree of the function? Choose all that apply. 04 05 0 6 07 08 09
