How Do You Calculate the Area Under the Curve f(x) = 9/x from 5 to 10?

Find the area of the region under the graph of the function f on the interval [5, 10].
F(x) = 9/x

When you say that F(x) = 9/x, do you mean that F'(x) = f(x) where f(x) is the function whose area under its curve you want to calculate? Or did you mistakenly capitalize "f"?

Well, my problem just says F(x). Other problems have F'(x), However, this one does not. Hmm...

Usually capitalized notation means that it is the anti-derivative. This means you should evaluate F from the given bounds. Do you know how to do this?

Try to be precise in the relationship between F(x) and f(x).
