At time t = 0, water begins pouring into an empty container at a constant rate. The water pours into the container until it is full. The situation is modeled by the given graph, where time, in seconds, is the independent variable and the depth of water in the container, in centimeters, is the dependent variable.

For which of the following containers would the graph be appropriate?

• A cylindrical container with uniform cross-section

• A container that is wider at the top than at the bottom

• A container that is narrower at the top than at the bottom

• A container with an irregular shape
