$y$ is a function of $x$

RECALL: If all vertical lines will pass through the graph in at most one point, then the graph represents $y$ as a function of $x$. Otherwise, the graph does not represent $y$ as a function of $x$. Notice that all vertical lines will pass through the graph in at most one point only. The graph passes the vertical line test. Thus, the given graph represents $y$ as a function of $x$.
