Answer :
Answer:
[tex](x+3)^2=4(y-3)[/tex]
Step-by-step explanation:
Parabolas
In conic sections, the standard form of a parabola with a vertex at (h, k) is
[tex](x-h)^2=4p(y-k)[/tex] ,
when the parabola is parallel to the y-axis (opens up/down);
[tex](y-k)^2=4p(x-h)[/tex],
when the parabola is parallel to the x-axis (opens left/right);
The distance between the vertex and the directrix (line) is the same as the distance between the vertex and the focus point, this distance is represented by "p".

Solving the Problem
Determine Which Standard Form to Use
The parabola opens downwards, so we use [tex](x-h)^2=4p(y-k)[/tex].
Identifying the Parabola's Equation
The parabola has a vertex at (-3, 3), so h = -3 and k = 3.
The distance between the vertex and focus point (-3, 2) is 1, so p = 1.
Putting it all together,
[tex](x-(-3))^2=4(1)(y-3)[/tex]
[tex](x+3)^2=4(y-3)[/tex].
