Answer 2

b

Answer 3

so an x can't have more than 1 y

Answer 4

For any given x value in (x,y) there can be one and only one corresponding y value

Answer 5

a isn't a function because when x = 1, the y is 3 and 5
c isn't a function because when x = 2, y is 3 and 4
and d isn't a function because when x = 0, y is 0 and 2, and when x = 2, y is 2 and 4

so it has to be b
