Question

Find the equation of a parabola with the vertex at (-3,-2) and directrix of X = 1

Answer 1

(y+2)^2= 4(x+3)^2

Answer 2

I think so

Answer 3

y = (x+3)^2 - 2

Answer 4

@Euler271 can you explain me how to get that equation?

Answer 5

you were thinking the equation of a circle.

y = a(x-h)^2 + k is the general equation of a parabola, where the point (h, k) is the vertex and a is the directrix.

Answer 6

nope, y ^2 = 4px with directrix x = 1( or p = 1) is it not from conic section?
