Answer:
{(3,6),(2,1),(-8,4),(2,0)}
Step-by-step explanation:
when determining if a set of points is a function
determine if any of the x values or y values repeat. if they do then it is not a function because it will not pass the function like test. (which is where you can draw a line trough the function and it will hit more than once.
none if the x values repeat and none if the y values do either.
x values : 3,2,-8,2
y values: 6,1,4,0
1) 0.4
2)0.875
i dont know the 3 and 4 one
(2.5, 2.5) and (2, 0)
But you knew that already
