To determine if a graph represents a function using the vertical line test, you need to observe whether any vertical line drawn on the graph intersects it at more than one point.

If a vertical line intersects the graph at no more than one point for every position along the x-axis, then the graph represents a function.

If you can visualize the graph (or if it’s described to you), apply the vertical line test:

  • If a vertical line touches the graph at only one point at every spot you examine, then the answer is Yes, it is a function.
  • If a vertical line touches the graph at more than one point at any location, then the answer is No, it is not a function.

Please refer to the specific graph or provide its description in order to give a definitive answer.
