Answer:
Situation 1 ----> Graph 3
Situation 2 ---> Graph 1
Situation 3 ---> Graph 2
Situation 4 ---> Graph 4
Step-by-step explanation:
Let's analyze each graph:
Graph 1. The graph shows how is the volume of a tank after some time. So, in this graph, we can see that it started full, then it was emptied and then it was filled again. This is because the graph is decreasing and then increasing.
Graph 2. The tank was always filled, however, it started slowly and after a while, they start to fill the tank faster. This is because the slope of the line becomes steeper.
Graph 3. The graph increase and then decrease, so the tank is filled and after a while is emptied.
Graph 4. It is increasing, then decreasing, and then increasing again. So, it is filled, then some water is out, and then it is filled again.
Therefore, each situation corresponds to:
Situation 1 ----> Graph 3
Situation 2 ---> Graph 1
Situation 3 ---> Graph 2
Situation 4 ---> Graph 4
