Answer

I can’t tell from your question alone — please upload the graph or describe the relations (shapes or points).

Explanation

To decide which graphed relation is a function, use the vertical line test: a graph represents a function if and only if no vertical line intersects the graph in more than one point. For discrete points, the relation is a function when each x-value appears at most once.

Quick steps you can use

  1. Draw or imagine vertical lines across the whole graph.
  2. If any vertical line hits the graph more than once, that graph is NOT a function.
  3. If every vertical line hits at most one point, it IS a function.

Common examples

  • A parabola opening up or down — passes (is a function).
  • A vertical line — fails (not a function).
  • A circle — fails (vertical lines cross twice unless tangent).
  • A straight non-vertical line — passes (is a function).
  • A set of points — check for repeated x-values.

Upload the graph or describe each option (e.g., “A: circle centered at (0,0), B: line y=2x, C: two points (1,2) and (1,3)…”), and I’ll tell you which is a function and why.
