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)=-x³ (x+4)² (x-7)

A. 0 , crosses the x -axis;
4 , touches the x -axis and turns around;
7 , crosses the x -axis
B. 0 , touches the x -axis and turns around;
4 , crosses the x -axis;
7 , crosses the x -axis
C. 0. crosses the x -axis:
-4 , touches the x -axis and turns around;
7 , crosses the x -axis
D. 0 , touches the x -axis and turns around;
-4 , touches the x -axis and turns around;
7 , crosses the x -axis
