Determine which of the following graphs does not represent a function
(Help me ASAP please)

Answer:
C
Step-by-step explanation:
In order to be a function, all of the graphs need to pass the vertical line test
Vertical line test- Only one point per vertical line, if there are more than one, it is not a function
C is the only one that has more than one point at a vertical line
The answer is c. If there are 2 points in a vertical line, it is not a function.
