請問為什麼答案是負無窮，感謝🙏

Solution The average profit is Vx X 4x - Vi AP(x) =4 Vx thousand dollars per hundred units. To find what happens at a very low level of pro- duction, we examine the limit of AP(x) as x +0: 4x - Vx 1 4 - 1/Vx becomes negative and lim = lim 4 - grows large in absolute value x³0 Vx lim AP(x) r0 x=0 x We interpret this limit as saying that as fewer and fewer units are produced, the average profit derived from producing each unit is actually a huge loss. This makes sense because when only a few units are produced, fixed start-up costs dominate any revenue that may be derived from sales.
