Does the following graph represent a function or a relation?

Text Solution

Verified by Experts

No matter where you try to draw a vertical line, it only hits the graph once, so this is a function.

The point (2, 1) is not filled in, indicating that the graph does not include the point (2, 1). However, notice that (2, 2) is completely filled in, because that point is included in the graph.
