y = -2x2 + 3x + 10
y = x2 + 6x + 10
y = -x2 - 6x - 15
y = 2x2 + 4x + 15
@jim_thompson5910 please explain this one?

telll me some things you already know about this parabola

anonymous · Answer

you can use -b/(2a) to find the vertex
and this is where I have been reading(im a visual learner so just let you know it is gonna take some time to help me, im sorry but I am willing to try)
