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

Explanation:

x = 1/12 (y/4 -4)^2 -5 or 1/12 (y/4 -4)^2 = x+5 x=112(y44)25or112(y44)2=x+5 or

1/12*1/16 (y -16)^2 = x+5 or 1/192 (y -16)^2 = x+5112116(y16)2=x+5or1192(y16)2=x+5 or

(y -16)^2 = 192 (x+5) or (y -16)^2 = 4*48 (x+5)(y16)2=192(x+5)or(y16)2=448(x+5).

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

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

Vertex is at (-5,16)
