Solution Steps

Step 1: Identify the included points

The graph includes all values greater than or equal to -1. Also, note that the point at -1 is shaded, which means it is included. The arrow indicates the interval continues to infinity. The point at 1 is represented by an open circle, thus it is not included.

Step 2: Express the interval in interval notation

The interval starts at -1 (inclusive) and goes to infinity. Thus, we can express the interval as: [-1, ∞)

Final Answer

\(\boxed{[-1,\infty)}\)
