The exemplar solution models how to apply the vertical line test, showing that when a vertical line is passed from left to right across a graph, it can intersect the graph at only one point for each input in order for the relation to be a function. Students will see that in this example there are two possible points that could be removed to satisfy this rule, and the reasoning for each choice is explained step by step. The lesson emphasizes that the vertical line test is a clear, visual way to verify that every input has exactly one unique output. This video aligns to Grade 8 Common Core Standard 8.F.A.1 and models the level of understanding all students should demonstrate.\n
