Green is 4 and Purple is 6 so you put it in a fraction by adding all of them and the just green and purple so 10/30 simplified is 1/3.
f(2) is three just look at where it says 2 on the x side of the table.
18 - h = 13 when h = -5
18 - (-5) = 13
18 + 5 = 13
23 = 13
False, h would need to equal +5
Hope this helps! ;)
