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)(x - 5)
A. x = 0, touches the x-axis and turns around; x = -2, crosses the x-axis; x = -5, crosses the x-axis B. x = 0, crosses the x-axis; x = 2, crosses the x-axis; x = 5, crosses the x-axis C. x = 0, crosses the x-axis; x = 2, touches the x-axis and turns around; x = 5, touches the x-axis and turns around D. x = 0, touches the x-axis and turns around; x = 2, crosses the x-axis; x = 5, crosses the x-axis
