A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches. Write a list of six ordered pairs to show the height of the candle in inches (y) as a function of time in hours )x) from the first hour after it started burning. For example, the point (0,8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs Is this relation a function? Justify your answer using the list ordered pairs made in the first part. If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function and explain the answer using input and output values.
