It should not be possible because the equation has two values for one X.
Now, from the math I've studied so far an equation where every variable is given a value (i.e. making a graph) it will only give you one answer, not two. Sure an equation can have multiple roots, but that's something else.
This graph is not possible.
(Now, I'm only 18 and I've so far passed Math level D at Swedish Upper Secondary High, so I might be wrong, but still.)
