Question

Write the equation of a parabola with a vertex at (0, 0) and a focus at (-4, 0). PLEASE HELP! I've tried, and just can't do it..sorry.

Answer 1

focus (p, 0)=(-4,0)
vertex (h.k) =(0,0)

x^2= (4p)*y
x^2 = 4*(-4)y
x^2 = -16y
1/-16x^2 = y

Answer 2

wait i did it wrong

Answer 3

x = -1/16y^2

Answer 4

y^2= (4p)*x
y^2 = 4*(-4)x
y^2 = -16x
1/-16y^2 = x
