Question

What is a reasonable domain for this situation?

Answer 1

Answer:

B

Step-by-step explanation:

The y-axis shows the number of gallons of water left (with respect to time).

The x-axis shows the time.

Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.

Looking at the choices, that is B, 0 ≤ x ≤ 12
