Step-by-step explanation:

Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)

Then you can use that equation to find h for d=-250:

  -250 = 0.25|h -1600| -400

  150 = 0.25|h -1600|

  600 = |h -1600|

This resolves to two equations:

__

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
