Answer:

  • functions: 2 graphs on the right
  • not functions: 2 graphs on the left

Step-by-step explanation:

If a vertical line can be drawn that goes through 2 or more points on the graph, then it is not a function. That will be the case for the two graphs on the left side of your figure.

The two graphs on the right side pass this "vertical line test," so are functional relationships.

upper left: not a function

upper right: is a function

lower left: not a function

lower right: is a function
