Solution

Solution Steps

Step 1: Identify where the limit does not exist but the function is defined

We need to find a point $a$ where $\lim_{x \to a} g(x)$ does not exist, but $g(a)$ is defined.
From the graph, at $x = 2$ , the function has a jump discontinuity, meaning the left-hand limit and right-hand limit are not equal, so the limit does not exist. However, $g(2)$ is defined.

Final Answer

$a = 2$

Step 2: Identify where the limit exists but the function is not defined

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.

Final Answer

$a = 4$

Step 3: Identify where both one-sided limits exist but the limit does not exist

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.

Final Answer

Smaller value $a = 2$ Larger value $a = 2$
