I need to find the focus on the parabola of this equation. Fan and medal for best answer!

OpenStudy (anonymous):

easier to write it as \[32y=(x-2)^2\] this tells you the vertex is \((2,8)\)

OpenStudy (anonymous):

now that it looks like \[4py=(x-h)^2\] you know \(p=8\)

OpenStudy (anonymous):

the focus is therefore \(8\) units directly above the vertex

OpenStudy (anonymous):

i had a typo there, i meant the vertex is \((2,0)\) not \((2,8)\) the focus, however, is \((2,8)\) 8 units above \((2,0)\)

OpenStudy (anonymous):

That doesn't appear as one of my choices though @satellite73

Wait isn't 36/4 = 9 and not 8?
