To find $f(-5)$ from the graph, we need to locate where $x = -5$ and determine the corresponding $y$-value on the curve.

1. On the graph, locate $x = -5$ on the horizontal axis.
2. From $x = -5$, trace vertically to the point on the curve.

From the graph, the point corresponding to $x = -5$ appears to be at $(-5, -20)$. Therefore, the value of $f(-5)$ is:

$f(-5) = -20$

Would you like more details or have any other questions?

Here are five related questions for practice:

1. What is $f(0)$ based on the graph?
2. What is $f(10)$ on the same graph?
3. Identify the interval where the function is increasing.
4. What is the range of the function shown in the graph?
5. At which $x$-value does the function have a maximum?

Tip: Always pay close attention to the scale on both the $x$-axis and $y$-axis of a graph; they might differ, affecting your interpretations.
