foci x^2=-y

Solution

foci

x^{2} = - y

Solution

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

Solution steps

Rewrite

x^{2} = - y

in the standard form:

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

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

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

p

from the center

(0, 0)

along the y-axis

(0, 0 + p)

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

Refine

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

Popular Examples

foci (y-2)^2=(x-1)^2+(y+4)^2 foci

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

foci x^{(2)}-6x+5y=-34 foci

x^{(2)} - 6 x + 5 y = - 34

foci x(2x+3)foci

x (2 x + 3)

foci 6x^2-49 foci

6 x^{2} - 49

foci x=+(y-4)^2-1 foci

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