    You 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 anti-derviateive for f(x). Then: \[\int\limits_{1}^{9}\sqrt{x}dx = F(x)\] where F(x) is evalauted on the inteval [1,9] meaning: \[F(b) - F (a) = F(9)-F(1)\]

    @amoodarya that's very helpful! Good job, but I think you should of let him try it out on his own first as this is a Calculus course which requires more critical thinking and application.

    If 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.

    It just occurred to me that the answer is wrong because I wanted it on the interval [1,9] not [0,9].
