does this problem make sense?

Hi, i have a homework problem that is the following:

Approximate the integral of (16/(x^2))dx using a Riemann sum with n=4, n=8

then, the teacher sent an email to us saying that for this particular problem, "integral must be from 0 to 2", those were his exact words. i dont know if i am interpreting this, but if one of them is 0, doesnt that mean that this whole thing is DNE (can't divide by 0). if i am wrong, i still do not know what to do, as i'm sure that theres more than one kind of Reimann Sum (left, right and middle).

any help is greatly appreciated
