PLEASE HELP ME ASAP Write the equation of the parabola with the given conditions.

A. focus (0, 1) and directrix x=3.

B. vertex (2, 4) and focus (0, 4)
vertex is (2, 4) so h=2 and k=4; focus(h+p, k)=(0,4)

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
