Answer:

Yes, it is a function

Step-by-step explanation:

anytime you want to test to see if the graph is a function, perform a vertical line test.

Basically if you drew a vertical line and the vertical line crosses the graph at only one point that means the graph is a function.

If it crosses on more than one point the graph is not a function.

Answer:

Function

Step-by-step explanation:

Two different X's could equal the same Y value so this is a function. Remember if there's multiple of the same input (x) equalling different outputs (y) then it is not a function. If there's multiple inputs (x) equalling the same output (y) it's just coincidence and works.
