Answer 1

Answer:

Step-by-step 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
