Enter your answer below. Be sure to show each step of your work.

Answer 1

Answer:
`(x+3)^2=-4(y-3)`

Explanation:

From the figure, it is downward parabola of the form
`x^2=-4ay`

The parabola has its vertex at
`(-3,3)`

Distance between parabola vertex and its directrix is 1 unit.

So, the value of a is 1

Hence, the equation of parabola is
`(x+3)^2=-4(y-3)`
