$\underset{x-\frac{1^{-}}{3}}{lim}j(x)=-$ and $\underset{x-\frac{1^{+}}{?}}{lim}j(x)=$

$\underset{x\frac{-}{(3{)}^{-}}}{lim}j(x)=$ and $\underset{x-\frac{1}{(3{)}^{+}}}{lim}j(x)=-$

$\underset{x\frac{1}{(3{)}^{-}}}{lim}j(x)=$ and $\underset{x\frac{1}{(3{)}^{+}}}{lim}j(x)=$

$\underset{x\frac{1}{(3{)}^{-}}}{lim}j(x)=-$ and $\underset{x\frac{1}{(3{)}^{+}}}{lim}j(x)=-$
