OpenStudy (xapproachesinfinity):
parabola has the maximum at the vertex if a<0 right
OpenStudy (xapproachesinfinity):
agree
OpenStudy (xapproachesinfinity):
yes , no?
what do you think
OpenStudy (xapproachesinfinity):
i hate when the poster just sits there waiting for an answer

do you know?
OpenStudy (xapproachesinfinity):
\(\Large (\frac{-b}{2a},f(\frac{-b}{2a}))\)
this is the vertex of any parabola
OpenStudy (xapproachesinfinity):
if a<0 f(-b/2a) is the maximum
if a>0 f(-b/2a) is minimum
