The equation of a parabola is given. y=
Here the value of 'a' = 18 and it is positive, it means the parabola opens up.
For vertical parabola the focus point is (h , k+p)
Where (h,k) is the vertex and p = (p is the distance between vertex and focus)
First we find vertex (h,k)
h =
a = 18 and b = 4
So h= = =
Plug in -1/9 for x and find out k
k =
=
=
So vertex is (, )
P = , we know a= 18
So p = =
Focus is ( h, k +p)
h = k =
and p =
k + P = +
Take common denominator 72
k + p = + = =
Focus point is ( , )

Your answer would be B. the closed circle on 25 includes the minimum age if 25 as where open would not. and to include any age above 25 you must shade to the right. hope this helps!!
