foci y^2=-8x

Solution

foci

y^{2} = - 8 x

Solution

(- 2, 0)

Solution steps

Rewrite

y^{2} = - 8 x

in the standard form:

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

(h, k) = (0, 0), p = - 2

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 + (- 2), 0)

Refine

(- 2, 0)

Popular Examples

x = y^{2} - 5

vertices y=x^2+2x-3 vertices

y = x^{2} + 2 x - 3

(x^2)/(25)+(y^2)/(36)=1

\frac{x ^{2}}{25} + \frac{y ^{2}}{36} = 1

vertices 2x^2 vertices

2 x^{2}

foci 4y^2-25x^2=100 foci

4 y^{2} - 25 x^{2} = 100
