Question

six graphs are shown below. click on the tabs to see them. graph 1 graph 2 graph 3 graph check the box corresponding to each graph that represents a function

Explanation:

To determine if a graph represents a function, use the vertical line test: any vertical line drawn on the graph should intersect the graph at most once. For this graph:

1. All vertical lines will intersect the graph at most one time. The closed/open endpoints do not create a case where a vertical line hits two points, as each x-value maps to only one y-value.

Answer:

This graph represents a function, so it should be checked.
