Answer:
x < -2
Explanation:
You want the domain of a function graphed as a curve with an open circle at x=-2, which is the right end of the curve.
Domain
The domain is the horizontal extent of the graph. It is the set of values for which the relation is defined.
Application
The open circle at (x, y) = (-2, 0) means that point is not part of the graph. All x-values to the left of that point have corresponding y-values, so the extent of the graph can be said to be ...
x < -2
The domain of the relation is x < -2.
