Question 5 (4 points) (04.01) Which of the following best defines a function? (4 points) A. A function is a special type of relation for which there is a rule that pairs each input with exactly one output.

B. A function is a relationship that defines the connection between two variables.

C. A function is a set of ordered pairs in which no y-value repeats.

D. A function pairs input and output values with no particular pattern.

Solve the system of equations using the substitution method. {y=−3x+7x=−2y−16 enter your answers in the boxes.

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.

B. two events are dependent if the occurrence of one event changes to occurrence of the second event. true or false
