Question

determine whether the following graph represents a function.

Explanation:

Step1: Recall the vertical line test

A graph represents a function if and only if every vertical line intersects the graph at most once.

Step2: Apply the vertical line test to the given graph

For any vertical line (a line parallel to the \( y \)-axis) drawn on the coordinate plane, we check how many times it intersects the given graph. Looking at the graph, no matter which vertical line we draw, it will intersect the graph at most once.

Answer:

Yes, the graph represents a function.
