A candle burns down at the rate of 0. 5 inches per hour. The original height of the candle was 9 inches. Part A: Write a list of 6 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, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points) Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points) Part C: If the rate at which the candle burned was 0. 45 inches per hour instead of 0. 5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points).
