Since the x-coordinates of the vertex and focus are the same that is -2, this is a regular vertical parabola. So, the standard form of the equation of a parabola with a vertical axis and vertex at `(h, k) ` is given by:


Here, vertex`(h,k)=(-2,3)`


So,` k+p=2(1)/2`

`rArr 3+p=2(1)/2`

`rArr p=5/2-3=-1/2`

Hence, `4p=4*-1/2=-2`

Since p is negative the parabola opens downward.

Now plugging the values of `(h,k)` and `4p` in the standard form of the equation of the parabola we get:


Therefore, the required equation of the parabola is `(x+2)^2=-2(y-3)` .
