Which of the following sets of points is a function?

{ (1,3) (1,5) (4,7) (8,9) }

{ (0,2) (2,5) (3,6) (3,8) }

{ (-2,3) (0,2) (1,3) (5,9) }

The following is not a function because:

Both 5 and 15 have a 2 as their output

The 9 is repeated in the output

The table is a function

15 has two arrows coming from it

1

Is this a function or a relation?

This is a relation because both x=-3 and x=4 go to y=0

This is a function because each x value only has one arrow coming out of it

This is a function becase each y value only has one x value

This is a relation because each x value has only one y value

1
