Answer with Step-by-step explanation:

Please check the dot on -2 on the given graph.

If the dot on -2 is shaded, then the domain is:  

{x | x ≥ -2}

This means that the solution included -2 and all the values to its right along the x-axis or +∞.

Interval notation:   [-2, +∞)

If the dot on -2 is NOT shaded, the domain is:

{x | x > -2 }

This means that the solution is greater than -2 and does not include 2.

Interval notation:  (-2, +∞)
