I need help with these questions please

Find the zeros for the given 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 - 14x2 + 49x The zero(s) islare . (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, ll in the answer box(es) within your choice. 0 A- There are two zeros. The multiplicity of the smallest zero is CI. The multiplicity of the largest zero is D. (Simplify your answers.) O 3- 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.) O C- There is one zero. The multiplicity of the zero is (Simplify your answer.) Determine the behavior of the function at each zero. Select the correct choice below and, if necessary, ll in the answer boxes within your choice. O A- 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 B. The graph touches the x-axis and turns around at all zeros. O C. The graph crosses the x-axis at all zeros. f(x + h) - f(x) Find the difference quotient of f; that is, nd h , h i 0, for the following function. Be sure to simplify. f(x)= -2x2+2x-1 w = D (Simplify your answer.)
