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 + 8)(x2 - 1)
A. x = 0, touches the x-axis and turns around;
x = 8, crosses the x-axis;
x = -1, touches the x-axis and turns around;
x = 1, touches the x-axis and turns around
B. x = 0, touches the x-axis and turns around;
x = -8, crosses the x-axis;
x = 1, touches the x-axis and turns around
