## anonymous 5 years ago find the average value of function f(x)=sqrt x; [1,8]

Do you know how to find average values using an integral?

2. anonymous

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?

4. anonymous

so the integral will be x ^3/2 / 3/2 right?

I believe that's correct, yes.

6. anonymous

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