Answer:

  (d)  D: [0, 60]; R: [-15, 0]

Step-by-step explanation:

The model is of the underwater portion of the net, so the only part of the graph we're interested in is that below the x-axis.

The x-intercepts of 0 and 60 define the bounds of the domain.

The range is the vertical extent of the graph in that domain, from y=-15 to y=0.

So, the domain and range are ...

  Domain: 0 ≤ x ≤ 60

  Range: -15 ≤ y ≤ 0
