Description

This example illustrates a scatter plot with several points labeled with their coordinates. The task is to determine whether the graph passes the vertical line test to qualify as a function. The solution demonstrates that no vertical line intersects the graph at more than one point, confirming that it is a function.

The Vertical Line Test is an essential concept in determining whether a graph represents a function. By drawing vertical lines across the graph, one can assess if any vertical line intersects the graph more than once, indicating it is not a function. The examples in this collection provide a visual and interactive way for students to comprehend this concept.

By observing multiple worked-out examples, students are better equipped to understand the nuances of a mathematical concept. These examples not only clarify the procedure but also reinforce understanding through varied applications.

Teacher’s Script: Let's examine this graph together. Notice how we apply the Vertical Line Test by imagining or drawing vertical lines through the graph. In this example, this image shows a scatter plot with several points labeled with their coordinates. the task is to determine whether the graph passes the vertical line test to qualify as a function. the solution demonstrates that no vertical line intersects the graph at more than one point, confirming that it is a function. What does this tell us about whether this is a function?
