Algebra
OpenStudy (misty1212):
to find the vertex, first coordinate is \(-\frac{b}{2a}\)
OpenStudy (misty1212):
in your case it is \[-\frac{-4}{2\times (-2)}=1\]

oops i meant \(-1\)
OpenStudy (anonymous):
My answer is B
OpenStudy (anonymous):
Then, yeah, just pick out the vertex a la @misty1212 . Since the highest exponent is 2, it has to be a parabola and only has 1 extrema
OpenStudy (anonymous):
@misty1212 am I right?
OpenStudy (misty1212):
yes
