1. **State the problem:** We are asked to evaluate limits and function values involving the sum $f(x) + g(x)$ at points $x=1$ and $x=2$ using the given graphs.
2. **Recall limit and function value rules:**
- The limit from the left, $\lim_{x \to a^-} f(x)$, is the value $f(x)$ approaches as $x$ approaches $a$ from values less than $a$.
- The limit from the right, $\lim_{x \to a^+} f(x)$, is the value $f(x)$ approaches as $x$ approaches $a$ from values greater than $a$.
- The function value $f(a)$ is the value of the function at $x=a$.
- For sums, $\lim_{x \to a} (f(x) + g(x)) = \lim_{x \to a} f(x) + \lim_{x \to a} g(x)$ if both limits exist.
3. **Evaluate each part:**
**a.** $\lim_{x \to 1^-} (f(x) + g(x))$
- From the graph, as $x \to 1^-$, $f(x)$ approaches the filled dot near 2.
- As $x \to 1^-$, $g(x)$ approaches the open circle near 0.
- Sum: $2 + 0 = 2$
**b.** $\lim_{x \to 1^+} (f(x) + g(x))$
- As $x \to 1^+$, $f(x)$ approaches the open circle near 0.
- As $x \to 1^+$, $g(x)$ approaches the filled dot near 4.
- Sum: $0 + 4 = 4$
**c.** $f(1) + g(1)$
- $f(1)$ is the value at the filled dot near 2.
- $g(1)$ is the value at the filled dot near 4.
- Sum: $2 + 4 = 6$
**d.** $\lim_{x \to 2^-} (f(x) + g(x))$
- As $x \to 2^-$, $f(x)$ is near the local max above 3, approximately 3.2.
- As $x \to 2^-$, $g(x)$ is decreasing linearly, near 3.
- Sum: $3.2 + 3 = 6.2$
**e.** $\lim_{x \to 2^+} (f(x) + g(x))$
- As $x \to 2^+$, $f(x)$ is near 3.
- As $x \to 2^+$, $g(x)$ is near 3.
- Sum: $3 + 3 = 6$
**f.** $f(2) + g(2)$
- $f(2)$ is the function value at $x=2$, near 3.
- $g(2)$ is the function value at $x=2$, near 3.
- Sum: $3 + 3 = 6$

- a. 2
