2. Use the polynomial function, P(x) = x4 – 2x3 – 7x² + 8x + 12 to answer the following questions: | How many zeros does this graph could possibly have without graphing it?

Find the x-intercepts of the polynomial function. State whether the graph crosses the x-axis, or touches the x-axis and turns around, at each intercept f(x)=x²-81x² OA. 0, crosses the x-axis; 9, crosses the x-axis -9, crosses the x-axis OB. O, touches the x-axis and turns around; 9. crosses the x-axis; -9, crosses the x-axis OC. O touches the x-axis and turns around; 81. touches the x-axis and turns around OD. O touches the x-axis and turns around; 81, crosses the x-axis b SAMSUNG Time Remaining: 01:22:59 Next 10:54 AM 3/15/2023

11) Tell the maximum number of zeros that the polynomial function may have. Then use Descartes' Rule of Signs to determine how many positive and how many negative zeros the polynomial function may have. Do not attempt to find the zeros. f (x) = 5x* – 3x³ + 2x² + 5x – 1
