1. **State the problem:**
We are given a piecewise function $f(x)$ and need to find for each $a = -5, -1, 2, 5$ the values of $f(a)$ and the limit $\lim_{x \to a} f(x)$ if they exist. If a value does not exist, we write "DNE".
2. **Recall definitions:**
- $f(a)$ is the value of the function at $x=a$ (the point on the graph).
- $\lim_{x \to a} f(x)$ is the value that $f(x)$ approaches as $x$ gets arbitrarily close to $a$ from both sides.
3. **Evaluate each point:**
- For $a = -5$:
- From the graph, $f(-5)$ is the function value at $x=-5$. The curve is continuous and smooth here, so $f(-5) = 1$.
- The limit $\lim_{x \to -5} f(x)$ is also $1$ since the function is continuous at $-5$.
- For $a = -1$:
- $f(-1)$ is the function value at $x=-1$. The graph shows a point at $y=-6$.
- The limit $\lim_{x \to -1} f(x)$ is $-6$ because the function approaches $-6$ from both sides.
- For $a = 2$:
- $f(2)$ is the function value at $x=2$. The graph shows a point at $y=1$.
- The limit $\lim_{x \to 2} f(x)$ is $1$ since the function is continuous and linear near $2$.
- For $a = 5$:
- $f(5)$ is the function value at $x=5$. The graph shows a point at $y=-2$.
- The limit $\lim_{x \to 5} f(x)$ is $-2$ because the function is continuous and linear near $5$.
4. **Summary:**
$$
\begin{array}{c|c|c}
a & f(a) & \lim_{x \to a} f(x) \\\hline
-5 & 1 & 1 \\
-1 & -6 & -6 \\
2 & 1 & 1 \\
5 & -2 & -2
\end{array}
$$
All values exist and are equal to the function values at those points.
