Find the average or mean slope of the function on this interval. By the Mean Value Theorem, we know there exists a c in the open interval (4, 8) such that f' (c) is equal to this mean slope. For this problem, there is only one c that works. Find it. Question Help: Message instructor Submit Question Jump to Answer MacBook Air
