Find the eq of Hyperbola whose eccentricity is and the distance between the focii is 16.
For a hyperbola, ,
eccentricity =
the foci are at a and -a, so distance between the two foci is 2a.
So now you know , simply put these values into the standard equation for a parabola.
Actually, technically speaking the answer should be where (f,g) is the centre, because any translation will not affect the eccentricity or distance between the foci.
