WebTechnically speaking, we can do a one-sided limit at each of the closed interval endpoints and get what is called a one-sided derivative. But the MVT is talking about a ordinary derivative, not a one-sided derivative. Thus, x=c must be on the open interval (a,b). There are other reasons why x=c lies on (a,b) not [a,b]. 1 comment ( 15 votes) Upvote WebJun 23, 2016 · Since the derivative of ex is just ex, application of the chain rule to a composite function with ex as the outside function means that: d dx (ef(x)) = ef(x) ⋅ f '(x) So, since the power of e is 1 x, we will multiply e1 x by the derivative of 1 x. Since 1 x = x−1, its derivative is −x−2 = − 1 x2. Thus, d dx (e1 x) = e1 x ⋅ ( − 1 x2) = −e1 x x2 エグモバ掲示板
