Question

Write the standard form of the equation of the parabola with the given focus and vertex at (0,0)
(0, -1)

Answer 1

im not sure what standard form is; but a parabola is geometrically defined as:


(y-h) = 4a(x-k)^2

where h,k is the vertex

and a is the distance from vertex to focus

Answer 2

i got me ha nd k backwards :/

Answer 3

(y-k) = 4a(x-h)^2

better

and of course with this you have to make adjustments for how it opens
