16) the revenue (in thousands of dollars) from producing x units of an item is modeled by
r(x) = 5x - 0.0005x2. find the marginal revenue at x = 1000.

17) the total cost to produce x units of paint is c(x) = (5x + 3)(7x + 4). find the marginal
average cost function.

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.
