The table below represents the atmospheric temperature at a location as a function of the altitude: Altitude (in thousand feet) x Temperature (in °C) f (x) 15 4 20 −6 25 −16 30 −26 The average rate of change of the function between x = 15 to x = 25 is degrees Celsius per thousand feet and represents the rate of change of temperature per thousand feet. (5 points)

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
