#### Answer

(a) $\lim_\limits{x\to 3}f(x)=-1$
(b) $f(3)=-1$

#### Work Step by Step

Recall that:
1. The limit as $x\to a$ on a graph is the $y$ value that the graph approaches as $x$ approaches $a$.
2. $f(a)$ is the $y$ values of the graph at $x=a$.
Using these rules, we observe the graph and find that:
(a) $\lim_\limits{x\to 3}f(x)=-1$
(b) $f(3)=-1$
