Graham is folding a piece of paper to make an origami figure. each time he folds the paper, the thickness of the paper is doubled. the paper starts out flat, with a thickness of 3 millimeters. a. write a list of six ordered pairs showing the output as the thickness of the paper when the input is the number of times it is folded. explain how you came up with your ordered pairs. b. is this relation a function? explain why or why not using the ordered pairs you came up with in part a.

Hello there again! 

The answer is 3,6,9,12,15,18.
How I came up with this ordered pair is taking the multiples of threethis relation is a function, because it is asking to list six ordered pairs showing the output of the thickness of the paper that he folds. The way that I came up with the ordered pairs in Part A is because you have to take the multiples of three or you could just take 6 and multiple it by 3 and you would get the same answer. 
And for B, this relation is not a function because the second set of numbers are not increasing by a fixed rate. 

Hope I helped!

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
