Question

1. does the graph represent a function?

a. yes - it is a function
b. no - it is not a function

Explanation:

Step1: Recall the vertical line test

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

Step2: Apply the vertical line test to the given graph

Looking at the graph, if we draw a vertical line (for some x - value), it will intersect the graph at more than one point (since the graph has a "loop" - like or curved part that would be crossed multiple times by a vertical line). So the graph fails the vertical line test.

Answer:

B. No - it is not a function
