Question

the following figure shows the entire graph of a relationship.

does the graph represent a function?
choose 1 answer:
a yes
b no

Explanation:

Step1: Recall Vertical Line Test

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

Step2: Apply Vertical Line Test

For the given linear graph, any vertical line (parallel to y - axis) will intersect the line at only one point. So the graph passes the vertical line test.

Answer:

A. Yes
