Homework Statement
find the focus and directrix of the parabola:
(y+2)^2 = 16(x-1)
Homework Equations
(y-k)^2= 4a(x-h)
focus: ( h+a,k)
vertex: (h,k)
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.
