For a graph of a relation to pass the vertical line test the line may only touch the graph:

• one time.
• two times.
• three times.
• not at all.

Is this graph a function or not a function? 

• Function 
• Not a Function

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

• Function
• Not a Function

• Function
• Not a Function
