Determine whether the graph is the graph of a function state

Determine whether the graph is the graph of a function, state why or why not.

Solution

Vertical Line Test : If you can draw a vertical line anywhere on a graph so that it hits the graph in more
than one spot, then the graph is NOT a function.

So, if we draw a vertical line it will interset the grap at 3 points.

So, graph is not a function
