Looking at the provided graph of the curve, we can break down the intervals of increasing, decreasing, and constant behavior.

a. Open intervals on which the function is increasing:

• The function increases as we move from the bottom-left of the graph toward the top-right. This occurs after the vertex, which is located at $x = -2$.
• Interval of increase: $(-2, \infty)$

b. Open intervals on which the function is decreasing:

• The function decreases as we move from the left towards the vertex at $x = -2$.
• Interval of decrease: $(-\infty, -2)$

c. Open intervals on which the function is constant:

• There are no intervals where the function remains constant, as the curve either increases or decreases throughout.
