I can’t see the image you mentioned. Could you upload it or describe it (graph, mapping diagram, or set of ordered pairs)?
How to decide whether something is a function:
- If it’s a graph: use the vertical-line test — if any vertical line intersects the graph more than once, it is NOT a function.
- If it’s a mapping diagram: each input (each element in the domain) must have exactly one arrow going out to the codomain. If an input has two arrows to different outputs or has no arrow at all (when the domain includes it), it’s not a function.
- If it’s a list of ordered pairs: no two pairs can have the same first coordinate with different second coordinates. If (x,y1) and (x,y2) appear with y1 ≠ y2, it’s not a function.
Send the image or describe the mappings and I’ll tell you True or False.
