11.3. Ernie and Bert study the functions n) n2 + 2n and 9(n) = mg. Ernie claims that the functions are asymptotically equal, so f ~ g. Bert insists that f can never be asymptotically equal to 9, since they always differ quite significantly, namely f (n) 9(a) 2 2n for all n ,3: 1. Explain why one is right and why the other is wrong
