Question

determine whether each graph represents a function. function not a function

Explanation:

Step1: Recall Vertical Line Test

A graph represents a function if every vertical line intersects the graph at most once. For a set of points, check if any two points have the same \( x \)-coordinate.

Step2: Analyze the Given Points

The given graph (set of points) has multiple points with the same \( x \)-coordinate (since they lie vertically aligned). So, a vertical line through that \( x \)-value would intersect multiple points.

Answer:

Not a Function (drag the point - graph to the "Not a Function" box)
