Question

Does this graph represent a function? Why or why not?​

Answer 1

Yes

Explanation:

Draw vertical lines parallel to the "y" axis and you will notice that they only cross the graph once. This only happens in function graphs.

Hope this helps

Answer 2

The graph represents a function

Explanation:

As you can observe, there is only one unique output assigned to every input. If an input contained 2 or more outputs, the relationship wouldn't be a function.
