2.
a paper airplane was thrown from the top of a tall building. the height of the paper airplane above the ground
can be found using the function f(x) = -1.5x + 69, where x is the time in seconds the airplane has been in the
air.
a. draw the graph of the function
b. how many seconds did it take the paper airplane to reach the ground?
c. explain your answer.

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.
