Answer:

[4] Function

[5] Not a function

[6] Function

Explanation:

The vertical line test is a test to determine if the line graphed is a function. Taking a vertical line, you move it left and right through the graph. If, at any point, there are two or more intersections in the vertical line, the graph is not a function.

4 and 6 pass the test meaning they are functions, 5 does not.
