Question

Find the equation of the parabola with focus (0,2) and directrix y = -2.

Answer 1

\[4py=x^2\] with directrix x = -p

substitute in and you'll have what you seek

Answer 2

thank you very much

Answer 3

oops, i mean directrix y = -p

Answer 4

its okay, thank you for your help

Answer 5

which form of the equation do you need?

Answer 6

what do you mean ?

Answer 7

standard form:\[ y = ax^2+bx+c\]

vertex form, with vertex @ (h, k):\[y=a(x-h)^2+k\]

Answer 8

i needed vertex form thank you for the formula

Answer 9

do you know the vertex?
