Suppose f(x) = 28.9 +1.5 log(x + 1) models salinity of ocean water to depths of 1000 meters at a certain latitude. x is the depth in meters and f(x) is in grams of salt per kilogram of seawater. Approximate the salinity (to the nearest hundredth) when the depth is 572 meters. A) -24.76 g/kg B) 78.21 g/kg 81.21 g/kg D) 33.04 g/kg
