Water is flowing into a tank. The function gives the depth of the water in meters when the volume of the water in the tank is cubic meters. It turns out that . Which statement best explains the meaning of .
When the volume is 10 cubic meters, the depth is 2 meters. As the volume increased from 0 to 10 cubic meters, the depth increased by 2 meters for every cubic meter of water. When the volume is 10 cubic meters, the depth will increase by 2 meters. As volume varies by a very small amount from 10 cubic meters, the depth of water increases by 2 times as much as the change in volume. The instantaneous rate of change of the depth’s value with respect to volume when the volume is 10 cubic meters is 2 meters per cubic meter.
