Do you know how to find average values using an integral?
I know.. but I have trouble in converting the sqrt of x to integral...
Ok, fair enough. Remember that \(\sqrt{x}\) is the same as \(x^{1/2}\). Does that help?
so the integral will be x ^3/2 / 3/2 right?
I believe that's correct, yes.

yes, in the end you should find the average value to be approximately 2.06
