<image>The policy of bringing household appliances to the countryside is an important measure to respond to the financial crisis and actively expand domestic demand. A home appliance manufacturing group in our province has proposed five transportation plans in order to achieve this goal as soon as possible. It is predicted that all five plans can complete the expected transportation task \(Q_0\) within the specified time \(T\). The function relationship between the total transportation volume \(Q\) and time \(t\) for each plan is shown in the figure. Among these five plans, the ones with gradually increasing transportation efficiency (transport volume per unit time) are____. (Fill in all the correct graph numbers)
