does the graph of this equation open up or down? how do you know Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The graph opens down, in other words,
it has a maximum, and not a minimum.
Suppose you had ,
The peak is at , and any value (+ or -)
of other than will make
less than the peak.
