Answer explanation

Choice C is correct. Each point x,y on the graph represents an elapsed time x , in hours, and the corresponding ocean water level y , in feet, at a certain loion based on the model. The graph shown passes through the points 0,0, 3,-12, and 6,0. Thus, the table in choice C gives the values of x and their corresponding values of y based on the model.

Choice A is incorrect and may result from conceptual or calculation errors.

Choice B is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect and may result from conceptual or calculation errors.
