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 + 3)(x2 + 1)
A. x = 0, touches the x-axis and turns around;
x = -3, 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 = 3, crosses the x-axis
C. x = 0, touches the x-axis and turns around;
x = -3, crosses the x-axis
D. x = 0, touches the x-axis and turns around;
x = -3, crosses the x-axis;
x = -1, touches the x-axis and turns around
