Please help me answer question 12

Find the zeros for the polynomial function and give the multiplicity for each zero. State whether the graph crosses the x-axis or touches the x-axis and turns around at each zero. f ( x ) = x3 +7x2-16x-112 Determine the zero(s), if they exist. The zero(s) is/are (Type integers or decimals. Use a comma to separate answers as needed.) Determine the multiplicities of the zero(s), if they exist. Select the correct choice below and, if necessary, fill in the answer box(es) within your choice. A. There is one zero. The multiplicity of the zero is (Simplify your answer.) O B. There are two zeros. The multiplicity of the smallest zero is . The multiplicity of the largest zero is (Simplify your answers.) O C. There are three zeros. The multiplicity of the smallest zero is . The multiplicity of the largest zero is . The multiplicity of the other zero is (Simplify your answers.) Determine the behavior of the function at each zero. Select the correct choice below and, if necessary, fill in the answer boxes within your choice. A. The graph touches the x-axis and turns around at all zeros. O B. The graph crosses the x-axis at x = .The graph touches the x-axis and turns around at x =. (Type integers or decimals. Simplify your answers. Use a comma to separate answers as needed.) O C. The graph crosses the x-axis at all zeros
