**Vertex is at #** (-5 , 16) #

Explanation:

#x = 1/12 (y/4 -4)^2 -5 or 1/12 (y/4 -4)^2 = x+5 # or

#1/12*1/16 (y -16)^2 = x+5 or 1/192 (y -16)^2 = x+5# or

# (y -16)^2 = 192 (x+5) or (y -16)^2 = 4*48 (x+5)#.

Comparing with standard equation of parabola #(y-k)^2=4a(x-h)#.

Vertex is at # (h,k) :. h= -5 , k= 16 #

Vertex is at # (-5,16) #
