The vertical line test is a graphical tool that is used in algebra for identifying the functions based on the graphs. The idea of identifying the vertical line test Algebra is PIck a function that assigns a single output Y value for each valid input which is the X value.
Imagine drawing a vertical line anywhere across the graph. If this vertical line intersects the graph represents a function. That means the specific X-value is corresponding with the Y-value.
If the vertical line interests the graph more than one point then only the graph does not represent the function. Here X value can’t have multiple Y values. These vertical lines visualize the relationships between X and Y graphs and confirm if the adhere is the definition of the functions.
