Below is the graph of a polynomial function with real coefficients. All local extrema of the function are shown in the graph. Fr Use the graph to answer the following questions. (a) Over which intervals is the function increasing? Choose all that apply. (-, -6) (-6, -3) (-3, 2) ○ (6,9) ○ (2, 9) (9,∞) (b) At which x-values does the function have local maxima? 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 06 07 ☐ 8 09 0.0,... ✗
