$$\lim_{x \to 3 }g(x)=3$$
Please note that the graph of $g(x)$ is the graph of $f(x)$ shifted up two units. To find $\lim_{x\to 3 }g(x)$, examine the graph of $g$ near $x=3$. As $x$ gets closer to $3$, the values of $g(x)$ get closer to $3$. We conclude from the graph that$$\lim_{x \to 3 }g(x)=3.$$
