<span> we have that
standard form of equation for parabola:
 (x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)

the answer is </span>(x+3)^2=-12(y-2)

Given the parabola whose equation is , find the focus and determine if the parabola opens up or down.
ziro4ka [17]
The equation of a parabola is:
y = ax {}^{2}  + bx + c
If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
( -  \frac{b}{2a}  \:  \:   \frac{1 - b {}^{2}  + 4ac}{4a} )
