**Problem 1 :**

Use the vertical line test to determine whether the following graph represents a function.

**Problem 2 : **

Use the vertical line test to determine whether the following graph represents a function.

**Problem 1 : **

Use the vertical line test to determine whether the following graph represents a function.

**Solution : **

**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.

**Problem 2 :**

Use the vertical line test to determine whether the following graph represents a function.

**Solution : **

**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.
