foci y^2=-4x

Solution

foci

y^{2} = - 4 x

Solution

(- 1, 0)

Solution steps

Rewrite

y^{2} = - 4 x

in the standard form:

4 (- 1) (x - 0) = (y - 0)^{2}

(h, k) = (0, 0), p = - 1

Parabola is symmetric around the x-axis and so the focus lies a distance

p

from the center

(0, 0)

along the x-axis

(0 + p, 0)

= (0 + (- 1), 0)

Refine

(- 1, 0)

directrix y^2=4x directrix

y^{2} = 4 x

directrix (y-7)^2=-12(x+1)directrix

(y - 7)^{2} = - 12 (x + 1)

foci x^2=-16y foci

x^{2} = - 16 y

x^{2}

foci ((x-3)^2)/5+((y-1)^2)/(15)=1 foci

\frac{( x - 3 ) ^{2}}{5} + \frac{( y - 1 ) ^{2}}{15} = 1
