Question

Is this a function, explain answer

Answer 1

No. There are two spots in the vertical line. (Vertical line test)

Answer 2

ANSWER

No, there are two points with the same x-coordinates.

EXPLANATION

The relation in the graph is not a function.

There are two points in the relation that have the same x-coordinates.

These points are (1,1) and (1,3).

As a result of this , a vertical line will intersect the graph of the relation at these two points.

Since the graph of the relation does not pass the vertical line test, it is not a function.
