Find the zeros 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(x + 2)(x2 - 1)

Question

A. x = 0, crosses the x-axis;
x = -2, crosses the x-axis;
x = -1, crosses the x-axis;
x = 1, crosses the x-axis
B. x = 0, touches the x-axis and turns around;
x = -2, crosses the x-axis;
x = 1, touches the x-axis and turns around
C. x = 0, touches the x-axis and turns around;
x = -2, crosses the x-axis;
x = -1, crosses the x-axis;
x = 1, crosses the x-axis
D. x = 0, touches the x-axis and turns around;
x = 2, crosses the x-axis;
x = -1, touches the x-axis and turns around;
x = 1, touches the x-axis and turns around
