To find the domain of the graph that includes the points (-1, -1), (0, 4), and (2, 8), we need to identify the range of x-values for these points.
The x-values for the given points are:
- For (-1, -1): x = -1
- For (0, 4): x = 0
- For (2, 8): x = 2
The smallest x-value is -1 and the largest x-value is 2. Therefore, the domain of the graph, represented as a compound inequality, is:
\[ -1 \leq x \leq 2 \]
