What is the best way to solve?

**Henry**, Saturday, February 16, 2013 at 8:34pmX = Xv = h = 3.

V(h,k)= V(3,1).

P(1,9)

Y = a(x-h)^2 + k

Y = a(1-3)^2 + 1 = 9.

4a + 1 = 9

4a = 9-1 = 8

a = 2.

Eq: Y = 2(x-3)^2 + 1

Axis: D(h,Y1), V(h,k), F(h,Y2).

Axis: D(3,Y1), V(3,1), F(3,Y2).

DV = k-Y1 = 1/4a = 1/8

1 - Y1 = 1/8

Y1 = 7/8.

VF = Y2-k = 1/4a = 1/8

Y2-1 = 1/8

Y2 = 1 1/8 = 9/8.
