The graph shown is a curve that appears to be continuous. To determine the domain of the graph, we need to identify the set of all possible $x$-values for which the graph is defined.

Analysis:

• The graph starts from a point on the left, crosses the x-axis, continues upward, and then curves back downward to the right.
• There don't appear to be any breaks, gaps, or undefined points in the curve along the x-axis.

Conclusion: The domain of the graph includes all real numbers, meaning that for every value of $x$, there is a corresponding $y$ value on the graph. This can be written in interval notation as:

$\text{Domain} = (-\infty, \infty)$

This indicates that the graph is defined for all $x$-values.
