Question

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.

Answer 1

Answer:

A: (1, 8.5)(2, 8)(3, 7.5)(4, 7)(5, 6.5)(6, 6)

B: Yes

C: Yes

Step-by-step explanation:

A: I obtained the ordered pairs by subtracting .5 inches from 9 inches for each second.

B: Yes because for every input there is only one output. For example after 2 seconds, the candle is 8 inches (and there is no other input). A function must only have one output for every input.

C: The relation would still be a function because for every input there would be one out put. Some new ordered pairs would be (1, 8.55) (2, 8.1) (3, 7.65) (4, 7.2) (5, 6.75) (6, 6.3)
