$$\underset{\mathit{x}\to 3^{+}}{\mathit{l}\mathit{i}\mathit{m}}\mathit{l}\mathit{n}\mid \mathit{x}-3\mid =-\mathrm{\infty }$$$$\underset{\mathit{x}\to 3^{-}}{\mathit{l}\mathit{i}\mathit{m}}\mathit{l}\mathit{n}\mid \mathit{x}-3\mid =-\mathrm{\infty }$$$$\Rightarrow \underset{\mathit{x}\to 3}{\mathit{l}\mathit{i}\mathit{m}}\mathit{l}\mathit{n}\mid \mathit{x}-3\mid =-\mathrm{\infty }$$$$\left(solimitexist\right)orno???$$
