Question details

sorry i have three questions to ask in this book

it said that  limit  x--> inf  iny =a^-2  implied  limit x->inf  y = e^(_a^2)
i think there is a proof to support such rule but it is not mensioned in the textbook
it seems reasonable to me but how can you actually prove it

(i cannot find a clear proof in the internet)
