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.
