A candle burns down at the rate of 0.75 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 O 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 0.5 inches per hour instead of 0.75 inches
per hour, would the relation be a function? Explain your answer using input and output values.
