(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

find the focus and directrix of the parabola:

(y+2)^2 = 16(x-1)

2. Relevant equations

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

focus: ( h+a,k)

vertex: (h,k)

3. The attempt at a solution

k=-2,h=1,a=16/4=4!,

vertex at (1,-2)

focus ( 5,-2)

does that mean that i solved the problem or do i still to do more work to reach the final answer? thanks in advance.
