Question

six graphs are shown below. click on the tabs to see them. check the box corresponding to each graph that represents a function. graph 1 graph 2 graph 3 graph 4 graph 5 graph 6 none of the graphs

Explanation:

Step1: Recall the vertical line test

A graph represents a function if every vertical line intersects the graph at most once.

Step2: Apply the vertical line test to Graph 4

For the given graph (Graph 4), if we draw any vertical line, it will intersect the graph at most one point. So, Graph 4 passes the vertical line test and represents a function.

Answer:

Graph 4 (the checkbox corresponding to Graph 4 should be checked)
