Best ResponseYou've already chosen the best response.1You are dealing with the fundamental theorem of calculus pt. II. According to FToC II Suppose f(x) is a contunuous function on an interval [a, b] which in your case is [1,9]. and supposed that F(x) is any antiderviateive for f(x). Then: \[\int\limits_{1}^{9}\sqrt{x}dx = F(x)\] where F(x) is evalauted on the inteval [1,9] meaning: \[F(b)  F (a) = F(9)F(1)\]

Best ResponseYou've already chosen the best response.1If there's any confusion, please ask. It's best to ask all the questions now and know for certain than be uncertain during an exam.

Best ResponseYou've already chosen the best response.0It just occurred to me that the answer is wrong because I wanted it on the interval [1,9] not [0,9].
