Let $$f(x) = \begin{cases} 6 & \text{ if } x \lt -2 \\ -x+ 4 & \text{ if } -2 \le x \lt 2 \\ 3 & \text{ if } x =2 \\ 4 & \text{ if } x \gt 2. \end{cases}$$ Sketch the graph of this function and find the following limits, if they exist.
(If a limit does not exist, enter DNE.)

1.	$\displaystyle \lim_{ x \rightarrow -2^{-}} f(x)$	=
2.	$\displaystyle \lim_{ x \rightarrow -2^{+}} f(x)$	=
3.	$\displaystyle \lim_{ x \rightarrow -2} f(x)$	=
4.	$\displaystyle \lim_{ x \rightarrow 2^{-}} f(x)$	=
5.	$\displaystyle \lim_{ x \rightarrow 2^{+}} f(x)$	=
6.	$\displaystyle \lim_{ x \rightarrow 2} f(x)$	=
