foci x=-1/8 y^2

Solution

foci

x = - \frac{1}{8} y^{2}

Solution

(- 2, 0)

Solution steps

Rewrite

x = - \frac{1}{8} y^{2}

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^{2} + y^{2} = 13

vertices (x^2)/(64)+(y^2)/(36)=1 vertices

\frac{x ^{2}}{64} + \frac{y ^{2}}{36} = 1

- 1 = x^{2} - y^{2}

y^{2} = - 12 x

foci y^2=8x foci

y^{2} = 8 x
