As it is symmetric about y-axis then its possible equation can be, x2= -4ay and x2=4ay but points(2,-3) lies in fourth quadrant then we will use the equation: x2=-4ay Putting the values of x=2 and y=-3 in above equation then we get: (2)*2=(-4a)×(-3) a=1/3 So,required equation of parabola, •x2=-4y/3
