one\ if applicable.

Explanation:

Step1: Recall constant - function definition

A function is constant on an interval if its $y$ - value does not change as the $x$ - value changes.

Step2: Identify constant intervals from the graph

Looking at the graph, we see that the function has a constant $y$ - value from $x=-1$ to $x = 1$ and from $x = 3$ to $x = 5$.

Answer:

$[-1,1],[3,5]$
