Answer:
Y=697
Step-by-step explanation:
Substitute the x with 225.
Y=3(225)+22
Therefore x equals 697
5w+12=67
-12 -12
5w=55
w=11
first, subtract 12 from both sides. second, divide 5 on both sides
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".
