Answer:

  y = -1/10x^2 -1/2

Step-by-step explanation:

The equation for a parabola with focus (a, b) and directrix y = d is ...

  y = 1/(2(b -d))(x -a)² +(b +d)/2

__

For the given focus and directrix, we have ...

  • a = 0
  • b = -3
  • d = 2
  • y = 1/(2(-3-2))(x -0)² +(-3+2)/2

Simplified, the equation is ...

  y = -1/10x² -1/2
