The dimensions of various-sized mirrors are created using the expression 0.5x – 2 for the width and 2x + 2
for the length. The function A(x) = x2 – 3x - 4
represents the area of the mirrors. The maximum
length of the mirrors is 52 centimeters.

How do the mathematical domain and reasonable
domain compare?

a. mathematical: {XER} reasonable: {x>0}

b. mathematical {XE R} reasonable: {x > 4)

c. mathematical: (x > 1.5) reasonable {x > 0)

d. mathematical (x > 1.5) reasonable (x > 4}

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.
