Part D is simply the mean value theorem for integrals as 5=3-(-2)... not too sure about E
Hi,
Sorry the title for this post should be: Real-valued function ON closed interval.
I am preparing to take the GRE subject test in math, and i am studying with a practice exam now. http://www.ets.org/Media/Tests/GRE/p...ctice_book.pdf. I am having a problem understanding #15. I have checked the answer, i had chosen D and it should be E.
I guess i have two questions:
1) Why is answer D always true. Does it just mean that the integral always exists, and because it always exists you can divide it by 5 to get M?
2) What does the limit in answer E mean? To me basically it reduces to 0/0 at the limit which i know doesn't exist, but if it is a limit h never reaches zero, so it should exist, right?
Hmm, thanks for any help with this.
