The graph you uploaded represents a function that is defined for values of $x$ starting from $-5$ and extending to positive infinity. The graph shows an open circle at $x = -5$, indicating that the function is not defined at that specific value, but is defined for all values greater than $-5$.

Thus, the domain of the graph is $x \geq -5$, which corresponds to the third option: $-5 \leq x < \infty$.

Would you like further clarification on this? Or do you have any additional questions?

Here are 5 related questions to consider:

1. How do open and closed circles in a graph affect the domain and range of a function?
2. What is the difference between a domain and a range of a function?
3. How do you identify the domain of a function from its graph?
4. Can the domain of a graph include negative values?
5. What is the significance of infinity in describing the domain of a function?

Tip: Always pay attention to whether the graph has open or closed circles at boundary points, as this will tell you whether those points are included in the domain.
