A sub is 7500 meters below sea level surfaces at rate of 80 meters per min. the depth of sub after m minutes is given by d(m) = -7500 +80m. give range and calculate domain.

80m = -7500

M = 90.3 domain

d = 80(0) -7500 = -7500 range

thanks for your help

**drwls**, Friday, December 16, 2011 at 8:48amThe range is d = -7500 to 0 meters, since it cannot go higher than sea level, and cannot be lower than it started out, while rising.

The domain is m = 0 to 93.75 minutes.

domain = 0 to 7500/80 or 0 to 93.75

range = -7500 to 0
