Question

help finding vertex, focus, directrix for parablola?

Answer 1

there are two forms:
(x-h)^2 = 4p(y-k)
(y-k)^2 = 4p(x-h)

in both forms, (h, k) is your vertex.
p is your distance from your vertex to your focus. it can also tell which way the parabola opens depending on whether its positive/negative. the directrix is just the opposite direction of the focus.

Answer 2

ok and what is h and what is k and p ??? i don't understand this part

Answer 3

h, k are the coordinates to your vertex.

Answer 4

ok i have an example do you wanna help me maybe i would understand it if you explain it :) and thank you for helping

Answer 5

yes..

Answer 6

ok it's asking to find the vertex, focus and directrix and the equations is : x^2 + 6y = 0

Answer 7

ok.. notice the x is squared so we have the first type: (x-h)^2 = 4p(y-k)

Answer 8

ok

Answer 9

this is your equation...
still with me?
