I can’t see the image you meant to attach. Could you re-upload it or type what it shows (a mapping diagram, a graph, or a list of ordered pairs)?

How to decide on your own:
- If it’s a mapping diagram: it is a function iff every input (each element in the domain) has exactly one arrow leaving it.
- If it’s a set of ordered pairs: it is a function iff no two different pairs have the same first coordinate (x) mapped to two different second coordinates (y).
- If it’s a curve/graph in the xy-plane: use the vertical line test — it’s a function iff every vertical line intersects the graph at most once.

If you paste or re-upload the picture (or list the pairs), I’ll tell you True or False and explain why.
