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
Answer:
B
