No, the graph does not represent a function because it does not pass the vertical line test.
<h2>What is a function?</h2>A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.
<h3>Vertical Line Test</h3>To pass the test, any vertical line that we draw on the graph should only touch one point.
A vertical line is a straight line that goes from top to bottom.
