Answer these questions for the poset ({2, 4, 6, 9, 12, 18, 27, 36, 48, 60, 72}, |). a) find the maximal elements. b) find the minimal elements. c) is there a greatest element? d) is there a least element? e) find all upper bounds of {2, 9}. f ) find the least upper bound of {2, 9}, if it exists. g) find all lower bounds of {60, 72}.

(a) maximal elements =27,48,60,72

(b) minimal elements =2,9

(c) greatest element =2,9

(d) least element = Does not exist

(e) upper bounds =18,36,72

(f) least upper bound =72

(g) lower bounds =2,4,6,12

(h) greatest lower bound =12

i can't solve unless i know what the line is

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
