Select all relations that represent functions.
(6,-6), (-3,12), (6,-1), (-8,13)

x y
0 0.5
2 1
1 2.5
0 2
(8,7), (7,8), (6,5), (5,6)
(-2,7), (-3,9), (-5,9), (-8,11)

x y
-3 0
-5 8
-7 8
-9 0

Answer 1

Explanation:

A function cannot have any repeating x values...they can have repeating y values, just not repeating x values.

so the first one that starts (6,-6) is NOT a function because there is repeating x values of 6.

the second one that starts (0,0.5) is NOT a function because there are repeating x values of 0

the third one that starts (8,7) IS a function because there is no repeating x values

the fourth one that starts (-2,7) IS a function..no repeating x values

the 5th one that starts (-3,0) IS a function...no repeating x values
