To determine the value of $f(-3)$, we need to locate the point on the graph where $x = -3$.

Looking at the graph:

1. Go to the $x$-axis at $x = -3$.
2. Move vertically to the point on the graph at that $x$-coordinate.

From observation, the point on the graph at $x = -3$ appears to be at $y = 2$.

Therefore, the value of $f(-3)$ is: $f(-3) = 2$

Would you like a detailed explanation of how to read function values from graphs?

Here are some related questions to explore this topic further:

1. How would you find $f(0)$ from this graph?
2. What does it mean if the graph crosses the $x$-axis?
3. How can you tell if a function is increasing or decreasing in a specific interval?
4. What is the maximum value of this function over the visible range?
5. How would you find the value of $f(4)$ from this graph?

Tip: When finding values from a graph, always start by locating the $x$-coordinate and then move vertically to the function's curve to read the corresponding $y$-value.
