Which of the following is NOT a function?
---
Look for 2 or more occurences of an x value with 2 different y values.
--------------------------
A. {(4,0), (0,-1), (2,0), (1,1), (3,0)}
x's are all different so it is a function.
-------------------
B. {(1,3), (2,3), (3,6), (4,6), (5,8)}
x's are all different so it is a function.
-------------------------------
C. {(3,1), (3,2), (6,3), (6,4), (8,5)}
x = 3 is repeated and has 2 different y values
Not a function.
--------------------------------------
D. {(6,4), (7,6), (8,4), (9,6), (5,4)}
x's are all different so it is a function.
==========================================
