one\ if applicable.

Explanation:

Step1: Recall increasing - function definition

A function $y = f(x)$ is increasing when as $x$ increases, $y$ also increases.

Step2: Analyze the graph

Looking at the graph, we see that the function rises from $x=-3$ to $x = 0$. The endpoints are included in the interval of increase since the function is continuous at those points.

Answer:

$[-3,0]$
