The function models the volume of liquid, in milliliters, in a container seconds after it begins draining from a hole at the bottom. According to the model, what is the predicted volume, in milliliters, draining from the container each second?
ExplanationShow
Choice D is correct. It’s given that the function models the volume of liquid, in milliliters, in a container seconds after it begins draining from a hole at the bottom. The given function can be rewritten as . Thus, for each increase of by , the value of decreases by , or . Therefore, the predicted volume, in milliliters, draining from the container each second is milliliters.
Choice A is incorrect. This is the amount of liquid, in milliliters, in the container before the liquid begins draining.
Choice B is incorrect and may result from conceptual errors.
Choice C is incorrect and may result from conceptual errors.
