Determine the limit$,$ if it exists, at the specified value of x by completing the tables. Round table answers to three decimal places.

limx$-2(-$x$2-4$x$-4)$

x $($from the left$)$f$($x$)-3-2\mathrm{.}5-2\mathrm{.}1-2\mathrm{.}01-2\mathrm{.}001$

x $($from the right$)$f$($x$)-1-1\mathrm{.}3-1\mathrm{.}9-1\mathrm{.}99-1\mathrm{.}999$

Does the limit exist? $?$Yes$$No$$

If so$,$ what is it$?($Leave blank if it does not exist.$)$
