An elevator travels down from the top floor of a skyscraper. Its height, in feet, is given by the equation h=950-27th=950−27t, where hh represents the elevator's height, in feet, and tt represents the time, in seconds. What could the number 950 represent in the equation? a height the elevator starts at.
b How long it takes for the elevator to reach the ground floor.
c How quickly the elevator descends, in feet per minute.
d The elevator's final height.

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.
