Answer:

(0,2) no folds

(1,4) 1 fold

(2,8) 2 folds

(3,16) 3 folds

(4,32) 4 folds

(5,64) 5 folds

(6,128) 6 folds

the (x) represents amount of folds, and the (y) represents the thickness in mm

Step-by-step explanation:

The graph is indeed a function, as if you were to do the straight line test on the 6 graphed points, no vertical line would intersect the graph in more than one spot.

if you treat the ordered pairs like this: (number of folds, thickness) you get (0,2), (1, 1), (2, 1/2) and keep going until you get six ordered pairs

for B, check to see if the x-values produce unique y-values. if so, then yes, it is a function. if not, then no, it is not a function
