All of them represent functions because x doesn't repeat

Answer 2

A. (20,10), (10,20), (-20,-10), (-10,-20)

B. (14,12) ,(10,8), (6,4), (2,0)

D. (0,-1) (5,-2) (10,-3), (15,-3)

Answer 4

anything that has two of the same x's is not a function because in a function there must be only one x to every y

A. (20,10) (10,20) (-20,-10) (-10,-20)
B. (14,12) (10,8) (6,4) (2,0)
C. (-7,-5), (-6,-3) (-5,-1), (-4,-1)
D. (0,-1) (5,-2) (10,-3), (15,-3)

as you can see, none of the x's repeat
are you sure that these are all the choices?

Answer 5
