Notice that any vertical line would pass through only one point of the two graphs shown in parts (a) and (b) of Figure 13. This video explains the concepts behind mapping a relation and the vertical line test. This simple activity gives students practice identifying horizontal and vertical lines from their equations and/or descriptions. Once we have determined that a graph defines a function, an easy way to determine if it is a one-to-one function is to use the horizontal line test. The x-axis is represented horizontally, the y-axis is represented vertically. The function in (a) is not one-to-one. When you have connected all of the points, you will be told if your graph is a valid graph of a function. One way is to analyze the ordered pairs, and the other way is to use the vertical line test. View DALANDIRA_PIERRE_-_Activity_6_Practice.pdf from BIOLOOGY 1 at Huntington High School.
