Answer explanation
Choice B is correct. It's given that the graph models the number of active projects a company was working on months after the end of November . Therefore, the value of that corresponds to the end of November is . The point at which is the y-intercept of the graph. It follows that the y-intercept of the graph shown is the point . Therefore, according to the model, the predicted number of active projects the company was working on at the end of November is .
Choice A is incorrect. This is the value of that corresponds to the end of November , not the predicted number of active projects the company was working on at the end of November .
Choice C is incorrect. This is the predicted number of active projects the company was working on months after the end of November .
Choice D is incorrect. This is the predicted number of active projects the company was working on months after the end of November .
