Is the Relation a Function? Yes Explanation: See solution.
Practice makes perfect
A graph represents a function if each and every x-value is paired with only one y-value. One way to see if a graph represents a function is to subject it to the Vertical Line Test. If there is any point where a vertical line would cross the graph more than once, the graph is not a function. Otherwise, the graph represents a function. Let's try with the given graph.
Each vertical line hits the graph at only one point, so it is a function.
