Which of the following graphs represents the quadratic function that has a vertex at zero, negative one?

Recall that a quadratic function will either have a maximum or a minimum vertex or turning point. For parabolas that open upward, they will have a minimum vertex. And parabolas that open downward will have a maximum vertex. Of our choices, options (A), (B), and (D) have a minimum vertex because they open upward. Options (C) and (E) open downward and therefore have a maximum vertex. But only option (D) has a vertex at zero, negative one.
