Let's try applying the vertical line test to the graph above to see if the equation represents a function.

Use the vertical line test to determine which graph represents a function. Here we have selected a simple one from many complicated vertical line test examples for you: You can use a pencil, your finger or the edge of a sheet of paper and. If the graph is not a function, enter dne.) y = 2 (d) if the graph represents a function, determine the intervals for which the function is increasing.

Use the vertical line test to determine whether or not a graph represents a function. Is a way to determine if a relation is a function. When a vertical line passes through the graph of a function, it will intersect the graph at only one point.

Draw a vertical line cutting through the graph. The approach is rather simple. The vertical line test can be used to determine whether a graph represents a function.

The vertical line test is a visual way to determine if a curve is a graph of a function or not. In the above graph, the vertical. States that if a vertical line intersects the graph of the.

If we can draw any vertical line that intersects a graph more than once, then the. If a vertical line is moved across the graph and, at any time, touches. If we can draw any vertical line that intersects a graph more than once, then the.

Drawing a vertical lines across the graph, we get. Every vertical line can only touch a graph once in order for the function to pass the vertical line test. If we can draw any vertical line that intersects a graph more than once, then the graph does not.
