# Explanation: ## Step1: Find left - hand limit as $x\to3^{-}$ As $x$ approaches 3 from the left side, we look at the values of the function $f(x)$ on the graph. The $y$ - value approaches 6. So, $\lim_{x\to3^{-}}f(x)=6$. ## Step2: Find right - hand limit as $x\to3^{+}$ As $x$ approaches 3 from the right side, the $y$ - value approaches 5. So, $\lim_{x\to3^{+}}f(x)=5$. ## Step3: Determine limit as $x\to3$ Since $\lim_{x\to3^{-}}f(x)\neq\lim_{x\to3^{+}}f(x)$, $\lim_{x\to3}f(x)$ does not exist. So, $\lim_{x\to3}f(x)=\text{DNE}$. ## Step4: Find $f(3)$ The open - circle at $x = 3$ means the function is not defined at $x=3$. So, $f(3)=\text{DNE}$. ## Step5: Find left - hand limit as $x\to6^{-}$ As $x$ approaches 6 from the left side, the $y$ - value approaches 2. So, $\lim_{x\to6^{-}}f(x)=2$. ## Step6: Find right - hand limit as $x\to6^{+}$ As $x$ approaches 6 from the right side, the $y$ - value approaches 2. So, $\lim_{x\to6^{+}}f(x)=2$. ## Step7: Determine limit as $x\to6$ Since $\lim_{x\to6^{-}}f(x)=\lim_{x\to6^{+}}f(x) = 2$, $\lim_{x\to6}f(x)=2$. ## Step8: Find $f(6)$ The closed - circle at $x = 6$ is at $y = 4$. So, $f(6)=4$. # Answer: $\lim_{x\to3^{-}}f(x)=6$ $\lim_{x\to3^{+}}f(x)=5$ $\lim_{x\to3}f(x)=\text{DNE}$ $f(3)=\text{DNE}$ $\lim_{x\to6^{-}}f(x)=2$ $\lim_{x\to6^{+}}f(x)=2$ $\lim_{x\to6}f(x)=2$ $f(6)=4$
