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

Answer:
The graph represents a function
Step-by-step 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.
Answer:
Yes
Step-by-step 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.
