i dont think so i understood why the answer is to be E
the question says that the function given in the 1st line is only for positive numbers and all the 4 options work for that...but it has clearly said that it wont work for negative numbers, hence E should be the one?
Can someone please explain the reasons for choosing E as the answer...
Note: Give me kudos if my approach is right , else help me understand where i am missing.. I want to bell the GMAT Cat
