The domain is the set of x values that has a corresponding y-values in a function or a graph.
The domain of the graph is:
From the graph (see attachment), we have the following observation
- The value of x starts from -10 (represented by the horizontal line from (-10,4) to (-4,4))
- The value x ends at 10 (represented by the slant line on the first quadrant)
These values can be represented as:
So, the domain of x is:
