Equation of the parabola is
Parabola is defined if `y<=2`
1. Vertex of the parabola
Thus vertex is (-4,2)
2 Since parabola is defined only if `y<=2`
This shows parabola open down.
3. Focus of the parabola
X=x+4 and Y=y-2
`Thus ` focus of the transformed parabola is (0,-3)
Thus focus of orinal parabola is (-4,2-3)=(-4,-1)
