.

Notice that the tree given points have the same y-coordinate equal to -2.


It means that the three points lie on straight line y = -2.


In turn, it means that you have, actually, degenerated quadratic function


    y(x) = -2


without quadratic term (the leading coefficient at the quadratic term is 0 (zero)).
