Good afternoon Candice!!!

For container B, observe that the bottom half of the container is wider than the top half. This means that the top half’s water level will increase at a much faster rate.

For container C, the height decreases at a constant rate, so the height will increase quadratically like an e^x or a positive x^2 graph.

Will draw this for you later.

Good afternoon Candice! You should plot these points on the graph for more accuracy. The shape of the graph should look something like this, but not as steep.
