Question

Does this image represent a function?

Answer 1

Answer:

The given image represents a function

Step-by-step explanation:

If you plot the given inputs and outputs on a graph, it's easier to see whether the given relation is a function.

The Vertical Line Test allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

Plotting the points of the given relation on a graph shows that there is only 1 point for each of the vertical lines (in purple) drawn on the graph. This means that the given relation passed the vertical line test, indicative of a function.
