Since each value of x is mapped to only one value of y, this graph represents a function.
<h3>When does a graph represent a function?</h3>
A graph represents a function when it has no vertically aligned points, that is, if <u>each value of x is mapped to only one value of y</u>.
This is one example of a graph without vertically aligned points, as if we traced vertical lines on the graph, they would cross the function only once, hence this graph represents a function.
A similar problem, in which we verify if a graph represents a function, is given at brainly.com/question/12463448
