Answer
The graph of the function is increasing in the following intervals:
$[-3,-2], [-1,0], [1,2], [3,4]$
The graph of the function is decreasing in the following intervals:
$[-4,-3], [-2,-1], [0,1], [2,3]$
The graph has upward concavity in the following intervals:
$[-3.5,-2.5], [-1.5,-0.5], [0.5,1.5], [2.5,3.5]$
The graph has downward concavity in the following intervals:
$[-4,-3.5], [-2.5,-1.5], [-0.5,0.5], [1.5,2.5]$
