QUESTION 11 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) = x4 - 144x2 x = 0, touches the x-axis and turns around; x = 144, touches the x-axis and turns around O x = 0, touches the x-axis and turns around; x = 144, crosses the x-axis O x = 0, crosses the x-axis; x = 12, crosses the x-axis; x = -12, crosses the x-axis O x = 0, touches the x-axis and turns around; x = 12, crosses the x-axis; x = -12, crosses the x-axis
