To determine if a graph represents a function, we can use the Vertical Line Test. This test states that if a vertical line intersects the graph at more than one point, then the graph does not represent a function.
Since I cannot see the image you're referring to, I will provide guidance on how you can determine if the graph represents a function on your own:
-
Draw vertical lines: If you can draw any vertical line that crosses the graph in more than one place, then the graph does not represent a function.
-
Check individual points: Each \(x\)-value should correspond to exactly one \(y\)-value for it to be a function.
If after applying the Vertical Line Test you find there are points where a vertical line crosses the graph more than once, the answer is Not a Function. If there are no such crossings, then the answer is Function.
Based on your provided options, choose accordingly.
