-12-11-10
-54312345
9 10 11 12
-10

Answer 1

9514 1404 393

Answer:

[-8, 4]

Explanation:

The domain is the horizontal extent of the graph. The left-most point is (-8, -8), which has an x-value of -8. The right-most point is (4, 8), which has an x-value of 4. The graph is continuous between these points, so has a domain of ...
