Use the graph below to determine the following limits (enter DNE if the limit does not exist):
lim x → − 2 − f ( x ) = {\displaystyle \lim _{x\to -2-}f(x)=}
lim x → − 2 f ( x ) = {\displaystyle \lim _{x\to -2}f(x)=}
lim x → − 1 f ( x ) = {\displaystyle \lim _{x\to -1}f(x)=}
lim x → 2 f ( x ) = {\displaystyle \lim _{x\to 2}f(x)=}
