Answer:
Increasing on: 
Decreasing on: 
Constant at : x=-1
Step-by-step explanation:
The given absolute value function is
.
A function is said to be increasing if for all
, 
From the graph, we can observe that the graph has a positive slope for all x-values less than -1. This implies that the interval of increase is
or 
We can also observe that, the slope of this function is negative on the interval:
or
.
At x=-1, the function is neither increasing nor decreasing. We say the function is constant at x=-1
