Answer:
![y=\dfrac{1}{8}(x-2)^2-4](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B1%7D%7B8%7D%28x-2%29%5E2-4)
Step-by-step explanation:
The directrix y=-6 is parallel to the x axes, so parabola has equation of the form
![(x-x_0)^2=2px(y-y_0),](https://tex.z-dn.net/?f=%28x-x_0%29%5E2%3D2px%28y-y_0%29%2C)
where
is the vertex of parabola and p is parabola's parameter.
By the definition,
is the distance from the vertex to the directrix, so
![\dfrac{p}{2}=2\Rightarrow p=4](https://tex.z-dn.net/?f=%5Cdfrac%7Bp%7D%7B2%7D%3D2%5CRightarrow%20p%3D4)
Hence, the equation of parabola is
![(x-2)^2=8(y+4)](https://tex.z-dn.net/?f=%28x-2%29%5E2%3D8%28y%2B4%29)
See attached diagram for the graph of parabola and its directrix.
In vertex form this equation is
![y=\dfrac{1}{8}(x-2)^2-4](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B1%7D%7B8%7D%28x-2%29%5E2-4)
