A scuba diver and his crew on deck spot some dolphins jumping in and out of the water as they swim through the ocean. Let the function D(x)= x 4 38 x 3 +519 x 2 3002x+6160 represent the path that the dolphins travel, where x represents the time since the start of travel and y represents the dolphins' distance above and below the surface of water. The scuba diver and his crew monitored the dolphins for a 20 second interval. At what times (in seconds) during this 20 second interval were the dolphins at the surface level? (Hint: Look for when x equals zero.)
