Graphs That Are Not Functions Examples. As pictured the x value 3 corresponds to more than one y value. Determine if a graph is a function or not learn with flashcards games and more for free.
Which graphs are functions. We now present examples of discontinuous functions. In this case symmetry is apparent so proceed to step 3.
The vertical line test a graph or set of points in the plane is a function if no vertical line contains more than one of its points.
Draw line y x and look for symmetry. If symmetry is noticeable double check with step 3. To graph the linear function we can use two points to connect the line. Yes the graph shows a function.
