(x-h)^2 = 4 a (y-k) vertex at (h,k) , vertex to focus is a
(x-2)^2 = 4 *1(y-5)
x^2 - 4 x + 4 = 4 y - 20
4 y = x^2 - 4 x + 24
etc
check
if x = 2, 4 y = 4 - 8 + 24 = 20 so y = 5
if x = 2, vertex to focus is a which is 1 so 6, good
What is an equation of a parabola with the given vertex and focus?
vertex:
(
–
2
,
5
)
; focus:
(
–
2
,
6
)
