Can you answer it now ??

anonymous · Answer

yes..thanks it was B and the answer to fill in the box is 1/5.

lastdaywork · Answer

Yes, the answer is B; but "The graph is compressed by a factor of" implies they have already considered compression & we just need to report 5.

I am not sure; notations causes trouble. :(
