Answer:
d) -4 ≤ x ≤ 1.5
Step-by-step explanation:
The domain is the horizontal extent of the graph. Here, it goes from about x=-4 to about x = 1.5.
There are solid dots on both ends of the line segment, so the inequality will use ≤ for both limits. The domain is ...
-4 ≤ x ≤ 1.5
- 1 1/3 - 2 1/5
= -4/3 - 11/5
= -20/15 - 33/15
= -53/15
= -3 8/15 mg/L
