a. Describe an appropriate domain and range for the function.
Choose the appropriate domain for the function below.
A.
The domain is all starting lengths of the candles burned or 0 inches to 5 inches.
B.
The domain is all times in which a candle would burn down or 0 minutes to 300 minutes.
C.
The domain is all times in which a candle would burn down or 0 hours to 300 days.
D.
The domain is all starting lengths of the candles burned or 0 inches to 50 inches.
Choose the appropriate range for the function below.
A.
The range is all times in which a candle would burn down or 0 minutes to 300 minutes.
B.
The range is all starting lengths of the candles burned or 0 inches to 50 inches.
C.
The range is all starting lengths of the candles burned or 0 inches to 5 inches.
D.
The range is all times in which a candle would burn down or 0 hours to 300 days.
Briefly discuss the validity of the graph as a model of the true function. Choose the correct answer below.
A.
The graph is a valid model of the function because length of a candle decreases as time a candle is burning increases.
B.
The graph is not a valid model of the true function.
C.
The graph is a valid model of the function because time a candle is burning decreases as length of a candle increases.
D.
The validity of the graph as a model of the true function can never be known.
