Answer:

Direction of the parabola: Down

Step-by-step explanation:

The value of the coefficient of x² (represented by <em>a </em>) determines whether the graph opens up or down.

* If <u><em>a</em></u> is positive, the graph opens <u>up</u>.

* If <u><em>a</em></u> is negative, the graph opens <u>down</u>.

Since the coefficient of  x² is -1, then it means that the graph of the parabola opens <u>downward</u>.
