Use the image to answer the question.
An illustration shows a coordinate plane with four quadrants. The x and y axes range from negative 6 to 6 in increments of 1. A semicircle is graphed on the plane. The semicircle passes through points plotted at coordinates left parenthesis 0 comma 6 right parenthesis, left parenthesis 6 comma 0 right parenthesis, and left parenthesis 0 comma negative 6 right parenthesis.
The graph of a relation is given. Apply the vertical line test to determine if this relation is a function.
(1 point)
The vertical line test is used to determine if a relation is a function. To apply the vertical line test, we need to see if there is more than one point on the graph that lies on the same vertical line.
Looking at the graph, we can see that for every x-coordinate, there is only one corresponding y-coordinate. This means that no vertical line can intersect the graph at more than one point. So, the relation passes the vertical line test and is indeed a function.
