# VERTICAL LINE TEST FOR FUNCTIONS WORKSHEET

Use the vertical line test to determine whether the following graphs represent functions.

Problem 1 : Problem 2 : Problem 3 : Problem 4 : Problem 5 : Problem 6 :  Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in at most one point, then the given graph represents a function.

Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in more than one point (three points), then the given graph does not represent a function.

Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in at most one point, then the given graph represents a function.

Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in more than one point (two points), then the given graph does not represent a function.

Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in more than one point (two points), then the given graph does not represent a function.

Step 1 :

Draw a vertical line at any where on the given graph. Step 2 :

We have to check whether the vertical line drawn on the graph intersects the graph in at most one point.

Step 3 :

In the above graph, the vertical line intersects the graph in at most one point, then the given graph represents a function.
