Question

Which of the following is not a function

Answer 1

Answer:

The first graph (ellipse) is not a function.

Step-by-step explanation:

Consider the provided graphs.

We need to determine which is not a function.

The vertical line test can be used to determine whether a graph represents a function.

If the vertical line intersect the graph more than one point then the graph is not a function.

Now consider the figure 1.

The first graph intersect the vertical line 2 times.

Therefore, the first graph (ellipse) is not a function.

Answer 2

The first curve represents the ellipse when we draw a vertical line there are 2 points of intersections.

The first graph which represents the ellipse is not a function.

What is the vertical line test?

The vertical line test is a method that is used to determine given relation is a function or not.

Firstly draw a vertical line then find the point of intersections.

1. The first curve represents the ellipse when we draw a vertical line there are 2 points of intersections.

Therefore, The first graph which represents the ellipse is not a function.

2.  The second curve represents the straight line when we draw a vertical line there is 1 point of intersections.

Therefore, The second graph represents a function.

3. The second curve represents the straight line when we draw a vertical line there is 1 point of intersections.

Therefore, The second graph represents a function.
