Question

HELP PLEASE PLEASE PLEASE!!!! write the standard form of the equation of the parabola whose directrix is y=-4 and whose focus is at (2,2)

Answer 1

\[\sqrt{(x_0-2)^2+(y_0-2)^2}=\left| y_0+4 \right|\]
\[(x_0-2)^2+(y_0-2)^2=(y_0+4)^2\]
simplify
\[x_0-4x_0-8=12y_0\]
->\[x^2/12-1/3x-2/3=y\]

Answer 2

if you need me to explain how to do this, tell me

Answer 3

( x - 2)² = 12 ( y +1)
