Hi,
How do you write the equation of the indicated conic in standard form?
Parabola: Vertex:(2,8) Directrix:Y =4 Opens Upward
The standard form is  , where the focus is (h,k + p)
(x-2)^2 = 4p(y -8) p = 4, 4p = 16
Hyperbola: Vertices:(-3,2),(7,2) Foci:(-5,2),(9,2) Opening Right and Left along y =2 C(2,2), a = 5
Foci:(-5,2),(9,2) f = 7 = sqrt(25 + b^2), b = sqrt(24)
