The function (n=
nr can be used to find the volume of air inside a basketball given its radius. what does v(r)
represent?
the radius of the basketball when the volume is v
the volume of the basketball when the radius is r
the volume of the basketball when the radius is v
the radius of the basketball when the volume is r

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.
