To solve the problem in the second image, we need to follow the same approach as shown in the first example. Here are the steps:

1. Locate the given x-coordinate: The question asks to find $f(-3)$, so we need to look for $x = -3$ on the x-axis.

2. Trace the corresponding y-value: After locating $x = -3$, trace vertically to the point on the curve. From the graph, it appears that the value of $y$ when $x = -3$ is $y = 3$.

Thus, $f(-3) = 3$.

Answer:

$f(-3) = 3$

Here are some related questions to further your understanding:

1. What does the value $f(x)$ represent on a graph of $y = f(x)$?
2. How do you interpret the maximum and minimum points on a graph of a function?
3. How do we determine the slope of the function between two points?
4. What is the meaning of the domain and range of a function on a graph?
5. How can you tell if a function is increasing or decreasing on a graph?

Tip: When working with function graphs, always ensure to carefully observe how the curve behaves around the points of interest for better accuracy.
