Find the x-intercepts 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)=3x-x A. 0, touches the x-axis and turns around; 3, crosses the x-axis OB. 0, touches the x-axis and turns around; 3. touches the x-axis and turns around OC. 0, touches the x-axis and turns around; 3, crosses the x-axis; -3, crosses the x-axis OD. 0, crosses the x-axis; 3, crosses the x-axis; -3, crosses the x-axis
