Vertex is #(0,0)#

Focus is #(0,-3/2)#

Eqn. of Directrix is #y=3/2, i.e., 2y-3=0#

For the Parabola #x^2=4by#, Vertex is #(0,0)#, Focus is #(0,b)# and

eqn. of Directrix is #y=-b#.

Here, #4b=-6 rArr b=-3/2#

ence, the Vertex is #(0,0)#

Focus is #(0,-3/2)#

Eqn. of Directrix is #y=3/2, i.e., 2y-3=0#
