A pool must be drained to complete repairs at the end of summer. The volume of water in the pool, in gallons, is modeled by the linear function w(t) = 483 - 23t, where t represents the time in hours. Determine and interpret the domain of the function. 0 t 21; the volume of water decreases from 21 to 0 gallons 0 t 21; the pool will drain from hours 0 to 21 0 t < 483; the volume of water decreases from 483 to 0 gallons 0 t < 483; the pool will drain from hours 0 to 483
