The question asks about the behavior of the function between $x = 0$ and $x = 3$. Based on the provided graph:

1. Between $x = 0$ and $x = 3$, the graph is decreasing (the $y$-values are getting smaller as $x$-values increase).
2. The function is non-linear in this interval, as the graph is curved.

Correct Answer:

It is decreasing and non-linear.

Would you like a detailed explanation of this behavior or additional clarification? Here are some related questions to expand your understanding:

1. How can you determine whether a function is linear or non-linear from a graph?
2. What is the definition of increasing and decreasing intervals in a function?
3. What other intervals on the graph display decreasing or increasing trends?
4. How can the slope of a tangent line help classify behavior (linear vs. non-linear)?
5. Can you determine if this function is continuous based on its graph?

Tip: Always examine the shape of the graph and the slope of the curve to classify the behavior accurately.
