OpenStudy (superhelp101):

Vertex: (3,-5) Directrix: y=7

OpenStudy (superhelp101):

@tkhunny could you help me out please?

OpenStudy (superhelp101):

like how did he get (3,17) for the focus? isn't it (3,12) ???

OpenStudy (tkhunny):

What's the question? You have the focus and directrix on the same side of the vertex. That's no good.

OpenStudy (superhelp101):

it says write the equation for each parabola with the given info which is Vertex: (3,-5) Directrix: y=7

OpenStudy (superhelp101):

wouldn't the y value for the focus be 12 not 17 ?
