Let’s evaluate the given values using the graphs provided.

1. Evaluate $f(1)$:

   • From the graph of $f(x)$ (the one on the left), look at the value of the function when $x = 1$.
   • The point corresponding to $x = 1$ on the graph of $f(x)$ is $(1, -1)$, so: $f(1) = -1$

2. Evaluate $g(-2)$:

   • From the graph of $g(x)$ (the one on the right), look at the value of the function when $x = -2$.
   • The point corresponding to $x = -2$ on the graph of $g(x)$ is $(-2, 4)$, so: $g(-2) = 4$

3. Evaluate $f(4) - g(-2)$:

   • From the graph of $f(x)$, there is no point corresponding to $x = 4$ (since the function isn't defined beyond $x = 2$). Thus, $f(4)$ is undefined.
   • For $g(-2)$, as found earlier, $g(-2) = 4$.
   • So, the expression $f(4) - g(-2)$ cannot be evaluated because $f(4)$ is undefined.

4. Find $x$ when $f(x) = -3$:

   • From the graph of $f(x)$, find the value of $x$ where $f(x) = -3$.
   • From observation, the point where $f(x) = -3$ occurs at $x = -2$.
   • Thus, $x = -2$ when $f(x) = -3$.

Summary:

• a) $f(1) = -1$
• b) $g(-2) = 4$
• c) $f(4) - g(-2)$ is undefined.
• d) $x = -2$ when $f(x) = -3$.

Would you like further details or clarifications?

Here are 5 related questions to consider:

1. What is the value of $g(0)$ from the graph?
2. What is the domain of the function $f(x)$?
3. For which values of $x$ does $g(x) = 0$?
4. Is the function $f(x)$ continuous for all $x$?
5. How would you describe the behavior of $g(x)$ as $x \to 4$?

Tip: When reading graphs, always pay attention to the scale and the defined domain to avoid misinterpretations!
