Determine the values of a, if any, for which all solutions of the differential equation y" (2a-11)y' + (a- 11a + 24)y = 0 tend to zero as too. Also determine the values of a, if any, for which all (nonzero) solutions become unbounded as t . There is no value of a for which all solutions will tend to zero as t. All solutions will tend to zero as t whenever: a Choose one There is no value of a for which all solutions will become unbounded as t . All (nonzero) solutions will become unbounded as to whenever: a Choose one
