The domain of the graph is x ≥ -4
How to determine the domain?
From the given graph, we have the following highlights:
- The x values start from -4
- The x value moves to the right of the graph (this means greater than)
- There is a closed circle at the smallest x value (this means equal to)
Greater than and equal to are represented by ≥.
This means that the symbol that completes the domain of the graph is ≥
Hence, the domain of the graph is x ≥ -4
