foci y^2=-x

Solution

foci

y^{2} = - x

Solution

(- \frac{1}{4}, 0)

Solution steps

Rewrite

y^{2} = - x

in the standard form:

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

(h, k) = (0, 0), p = - \frac{1}{4}

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 + (- \frac{1}{4}), 0)

Refine

(- \frac{1}{4}, 0)

Popular Examples

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

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

foci 4x^2+48y+12x=159 foci

4 x^{2} + 48 y + 12 x = 159

foci y=2x^2+5x-3 foci

y = 2 x^{2} + 5 x - 3

foci (x+9)^2=-40(y-7)foci

(x + 9)^{2} = - 40 (y - 7)

foci y=x^2-14x-49 foci

y = x^{2} - 14 x - 49
