  1. To determine which relation is a function, we can use the Vertical Line Test. This test states that if a vertical line intersects the graph at more than one point, the relation is not a function.

    A) If a vertical line can touch the graph at more than one point, it is not a function.

    B) Check similar to A.

    C) If it passes the Vertical Line Test, it is a function.

    D) Again, same method as above.

    Without seeing the specific graphs, I recommend checking each graph against the Vertical Line Test. The correct answer is the one graph that passes this test, meaning any vertical line drawn does not intersect it at more than one point. If you can provide more information about the graphs, I’ll be glad to assist further! For in-depth assistance, consider checking the extended services page.
