Question 50 of 50 Choose two statements (the original conditional statement and its converse)
that could form the biconditional "x = 1 if and only if x- 1 = 0."
O A. If x = 1, then x-1=0.
B. If x = 1, then x- 1 = 0.
O c. If x- 1 = 0, then x = 1.
O D. If x= 1, then x-1=0.

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.
