So what makes a function a function is that each input (x) only has one output (y).
Set A is not a function because when x = 2, y = -2 and 3.
Set B is not a function because when x = 9, y = 3 and -3.
In short, the correct option is "Neither A nor B".
There were 4 adults that went on the field trip.
Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1 collect like terms
3x-x=-1-3
2x=-4 divide both side by 2
x=-4/2=-2
