Answer: Three points
Step-by-step explanation:
(-3,2) (-3,3) (1,4) (1,-4) (2,-4) (2,-2)
Looking at these points we could say there all doesn't represent a function because each input doesn't exactly assigns one output.
for example -3 the input assigns two different outputs 2 and 3
1 the input also assigns two different outputs 4 and -4
and lastly 2 the input assigns two different outputs -4 and -2
This makes it not a function but if we take away the coordinates
(-3,3) ( 1,-4) and (2,-4) it becomes a function because you will have the coordinates (-3,2) (1,4) (2,-2) and as you could see every input has exactly one output.
