The mean value theorem applies to a function ƒ over an interval [,] under the conditions that ƒ is differentiable over (,) and continuous over [,]. Can you adjust the curve and boundary points so that there are no X points shown? After applying the Lagrange mean value theorem on each of these intervals and adding, we easily prove 1. The curve can be modified by moving the black points. While the Mean Value Theorem has practical use (for instance, the speed monitoring application mentioned before), it is mostly used to advance other theory. The point (c, f (c)), guaranteed by the mean value theorem, is a point where your instantaneous speed — given by the derivative f´(c) — equals your average speed. So, essentially, is we knew that f (a) was 3 and f (b) was 15, the Mean Value Theorem tells us that the function f takes on every value between 3 and 15 somewhere between a and b on the x-axis, as long as the two points (1 & 2) above are true for f.
