Find the ve

Answer :

Given equation of the parabola is 4(y - 1)2 = - 7(x - 3)




Comparing with the standard form of parabola (y - a)2 = - 4b(x - c) we get,




The vertex is (c, a) = (3, 1)


The focus is (- b + c, a) =


The equation of the axis is y - a = 0 i.e, y - 1 = 0


The equation of the directrix is x - c = b


Directrix is


Directrix is


Directrix is
