Vertical Line Test
The Vertical Line Test is a fundamental concept in mathematics, particularly in the study of functions and relations. It serves as a method to determine whether a given curve represents a function or not. By visually examining whether any vertical line intersects the curve at more than one point, one can ascertain whether the corresponding relation is a function. This test is indispensable in various mathematical applications, aiding in the analysis and classification of functions, thus forming a cornerstone in understanding the behavior and properties of mathematical models.
