Question

What is the equation of the parabola, in vertex form, with focus at (2,-4) and directrix y = -6?

Answer 1

\[(x-2)^{2}=\frac{ 1 }{ 4}(y+5)\]\[(x-2)^{2}=4(y+5)\] \[(x+2)^{2}=\frac{ 1 }{ 4}(y+4)\]\[(y+4)^{2}=-4(x-2)\]

Answer 2

Is it the first answer?

Answer 3

oh the first answer is also -1/4
