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 - 4)(x - 6)
A. x = 0, touches the x-axis and turns around;
x = -4, crosses the x-axis;
x = -6, crosses the x-axis
B. x = 0, crosses the x-axis;
x = 4, crosses the x-axis;
x = 6, crosses the x-axis
C. x = 0, crosses the x-axis;
x = 4, touches the x-axis and turns around;
x = 6, touches the x-axis and turns around
D. x = 0, touches the x-axis and turns around;
x = 4, crosses the x-axis;
x = 6, crosses the x-axis
