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. O, crosses the x-axis; 9, crosses the x-axis -9, crosses the x-axis OB. 0, 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

Choose the end behavior of the graph of each polynomial function. what is the correct answer for A, B, and C?

Find the zeros for each 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 (z) = a + 7z - 4x - 28 %3D O x=2: has multiplicity 1, and it touches the x-axis. x-2: has multiplicity 1, and it touches the x-axis. x-7: has multiplicity 1, and it touches the x-axis. O x-2: has multiplicity 3, and it crosses the x-axis. x-2: has multiplicity 3, and it crosses the x-axis. x=-7: has multiplicity 3, and it crosses the x-axis. x-2: has multiplicity 1, and it crosses the x-axis. x--2: has multiplicity 1, and it crosses the x-axis. X--7: has multiplicity 1, and it crosses the x-axis. O x-2: has multiplicity 1, and it crosses the x-axis. x--2: has multiplicity 2, and it touches the x-axis. X-7: has multiplicity 2, and it touches the x-axis.

Decide whether the function is a polynomial function. If so, write it in standard form and state it’s degree, type, and leading coefficient
