Let f(x)={2x+4ifx33x+13ifx=3\displaystyle {f{{\left({x}\right)}}}={\left\lbrace\begin{array}{ccc} \sqrt{{-{2}-{x}}}+{4}&\text{if}&{x}\ne-{3}\\{3}{x}+{13}&\text{if}&{x}=-{3}\end{array}\right.}
Calculate the following limits. Enter "DNE" if the limit does not exist.
limx3  f(x)=\displaystyle \lim_{{{x}\to-{3}^{{-}}}}\ \ {f{{\left({x}\right)}}}=  

limx3+  f(x)=\displaystyle \lim_{{{x}\to-{3}^{+}}}\ \ {f{{\left({x}\right)}}}=  

limx3  f(x)=\displaystyle \lim_{{{x}\to-{3}}}\ \ {f{{\left({x}\right)}}}=  

f(3)=\displaystyle {f{{\left(-{3}\right)}}}=
