Use the figure below, which gives a graph of the function $f(x)$, to give values for the indicated limits. If a limit does not exist, enter none.
(a) $\lim\limits_{x \rightarrow -2} f(x)$ = help (limits)
(b) $\lim\limits_{x \rightarrow 0} f(x)$ =
(c) $\lim\limits_{x \rightarrow 2} f(x)$ =
(d) $\lim\limits_{x \rightarrow 3} f(x)$ =
