Eccentricity pertains to each conic section and is representative of the deviation from being circular. The conic sections are therefore combined in the determination of the eccentricity based on a fixed point.

a million use distance formulation 2 all have eccentricity except circles; if e=a million that is a parabola, if e < a million that is an ellipse and if e > a million that is a hyperbola 3. vertex style is y - ok = a million/(4p) (x - h)^2 the position p = directed distance from vertex to concentration, 4p = length of latus rectum, and (h,ok) = vertex. So for y = 5(x+2)^2 + 7 or y - 7 = 5(x + 2)^2, the vertex is (-2,7) 5 = a million / 4p so a million = 20p; p = a million/20 so concentration = (-5, 7 + a million/20) directrix: y = 7 - a million/20 L.R. = 4/20 = a million/5

Most people assign it to the ellipse.
