If a ball is thrown upward at 64 feet per second from the top of a building that is 120 feet high, the height of the ball is given by s = 120 + 64t − 16t2 feet where t is the number of seconds after the ball is thrown. how long after it is thrown is the height 120 feet?

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.
