Use the equation to determine whether the parabola opens upward or downward. 
A) upward 
B) downward

Quizplus · Accepted Answer

To determine the direction of opening, we look at the coefficient of the $x^2$ term in the equation. If it is positive, the parabola opens upward, and if it is negative, the parabola opens downward. In this case, the coefficient is negative, so the parabola opens downward.
