Do the sets of student's data represent a proportional relationship?
O A. Both sets of data are proportional because both students' ratio of laps to time is constant.
O B. Neither set of data is proportional because the data sets do not begin with (0,0).
O C. Wayne's data is proportional because his ratio of laps to time is constant.
OD. Ryan's data is proportional because his ratio of laps to time is constant.

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.
