Hi,
Standard Form of an Equation of an Ellipse is
where Pt(h,k) is the center. (a variable positioned to correspond with major axis)
a and b are the respective vertices distances from center
(0, -1) and (12, -1), C(6,-1) and minor axis of length 6. b = 3
the vertex form of a Parabola opening up(a>0) or down(a<0),
where(h,k) is the vertex and x = h is the Line of Symmetry
x = -3 is the Line of Symmetry
