Question

( begin{aligned} operatorname{lt} frac{e^{1 / x}-1}{x+0} frac{e^{1 / x}}{e^{1 / x}+1} &=ln frac{1-e^{-1 / x}}{1+e^{-y x}}=frac{ln 1-frac{1}{e^{1 / x}}}{x+0}-frac{1}{1+frac{1}{e^{1 / x}}} =frac{1-0}{1+0} & text { (Ophoub } end{aligned} )

# lim x 20 ex +1 (b) 1 (a) 0 (c)-1 (d) Does not exist
