A parabola with a negative leading coefficient opens downward, so its vertex gives a:
AMinimum
BMidpoint
CMultiple
DMaximum
Answer & Solution
Correct answer: D. Maximum
1. Opening downward means the arms fall away on both sides.
2. The turning point is then the highest point reached.
3. So the vertex gives a maximum.
