\( a = 2 \)
- We need to find a point \( a \) where \( \lim_{x \to a} g(x) \) exists, but \( g(a) \) is not defined.
- From the graph, at \( x = 4 \), the function has a hole, meaning the limit exists as the left-hand limit and right-hand limit are equal, but \( g(4) \) is not defined.
\( a = 4 \)
- We need to find a point \( a \) where \( \lim_{x \to a^-} g(x) \) and \( \lim_{x \to a^+} g(x) \) both exist, but \( \lim_{x \to a} g(x) \) does not exist.
- From the graph, at \( x = 2 \), the left-hand limit and right-hand limit exist but are not equal, so the overall limit does not exist.
