Question

limit[2/(1+e^-(1/x))] as x approach 0^+

Answer 1

\[\lim_{x\to 0^+}{2\over1+e^{-1/x}}\]looks to me like you can just consider\[\lim_{x\to 0^+}e^{-1/x}\]and that should show your answer

Answer 2

am failing to understand what you are saying, cn explain further

Answer 3

look at\[\lim_{x\to 0^+}\frac1x\]what does that approach?
