OG详解-OG6 数学1 Q15

Choice B is correct. It’s given that the graph models the number of active projects a company was working on x months after the end of November 2012. Therefore, the value of x that corresponds to the end of November 2012 is 0. The point at which x = 0 is the y-intercept of the graph. It follows that the y-intercept of the graph shown is the point (0, 5). Therefore, according to the model, the predicted number of active projects the company was working on at the end of November  2012 is 5.
Choice A is incorrect. This is the value of x that corresponds to the end of November 2012, not the predicted number of active projects the company was working on at the end of November 2012. Choice C is incorrect. This is the predicted number of active projects the company was working on 2 months after the end of November 2012. Choice D is incorrect. This is the predicted number of active projects the company was working on 4 months after the end of November 2012.
