State the open intervals where each function is increasing,
decreasing, or constant.

The interval on which the function is descreasing is (-infinity , 0)The interval on which the function is increasing is : (0 , infinity)The interval on which the function is constant is : ( 0,0 )

Step-by-step explanation:

From the graph, we can see that:

The domain are all real numbers, (R)

The interval on which the function is descreasing is (-infinity , 0)The interval on which the function is increasing is : (0 , infinity)The interval on which the function is constant is : ( 0,0 )

Hope it will find you well.
