Answer:
Step-by-step explanation:
The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.
For a left-opening parabola:
x = a(y-k)²+h,
a < 0,
vertex (h,k)
focal length p = 1/|4a|
focus (h-p, k)
directrix: x=h+p
Apply your data
focus (1,-4)
directrix x=2
vertex (1.5,-4).
focal length p = 0.5
a = -1/|4p| = -½
x = -½(y-2)²+ ½
Answer:
f(x)= -2(x^2-x-6)
Step-by-step
The original formula is f(x)=a(x-h)+k
1) Plug the negative 2 in for a
2) multiply (x-3)(x+2)
3) plug your answer in for 2 in for the parentheses
