How do you know if a graph is a function?

Understand the Problem

The question is asking us to identify the criteria that determine whether a graph represents a function. It is necessary to consider characteristics of functions, particularly the vertical line test, which states that if any vertical line intersects the graph more than once, then the graph does not represent a function.

Use the vertical line test: a graph is a function if every vertical line intersects it at most once.

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

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

Vertical Line Test: This is a standard method of determining if a graph is a function. If any vertical line crosses the graph more than once, then it is not a function.

Tips

A common mistake is confusing the vertical line test with the horizontal line test, which is used to determine if a function is one-to-one.
