The grass on Julie's lawn was 4.5 centimeters tall right after she mowed it. Then the grass grew at a rate of 2.1 centimeters per week.
Which equation models the relationship between h, the height of the grass in
centimeters, and w, the number of weeks since Julie mowed?
O w = 2.1h + 4.5
O w = 4.5h + 2.1
O h = 2.1w. + 4.5
O h = 4.5W + 2.1

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.
