Answer:
Hey there!
A. Function
B. Function
C. Not a function
The vertical line test says that if you can draw a vertical line with two points or more on the line, then the graph is not a function.
Let me know if this helps :)
A is a function because if you draw a line through it the vertical line only intersects the graph’s line once
B is also a function because the vertical line only intersects the graph’s line once, no matter where you put the vertical line
C is not a function because the vertical lines passes through two points on the line, not one
