Answer 1

I'm trying to figure out the order in which these people speak.

Answer 2

So, you're saying that the function is decreasing?

Answer 3

If this is true -->"The table shows as more people come, the less time they speak," then the function is decreasing.

I don't see any reason to assume that the two people who speak 11 minutes each came first to speak in the presentation.

How do we know that a person who spoke for just 2 minutes did not speak first?

Answer 4

Maybe we should accept that the question is poorly written and try to get a linear regression out of the data.

Answer 5

So, using the points (2,11); (3,8); (4,5); (5,2) from the table, your conclusion that the function is decreasing is correct.

Using this online regression calculator:

http://easycalculation.com/statistics/regression.php

gives that the data points are linear with equation: y = 17 - 3x.

I would go with linear and decreasing based on what is given in the problem.
