Question

When given a graph, the vertical line test can be used to determine functionality. Describe the vertical line test and explain the reasons why the graph does, or does not, represent a function

Answer 1

The vertical line test is when you put vertical lines down the graph and if the point does not touch the line more than once, it passes and represents a function.

Answer 2

Answer:

Draw vertical lines to intersect on a graph. The relation is a function if there’s only one point of intersection on a graph. The relation is not a function if there’s more than one point of intersection on a graph. The vertical line test is used to determine if each input has exactly one output.
