foci y=-1/4 x^2

Solution

foci

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

Solution

(0, - 1)

Solution steps

Rewrite

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

in the standard form:

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

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

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 + (- 1))

Refine

(0, - 1)

Popular Examples

foci y=9x^2+24x+16 foci

y = 9 x^{2} + 24 x + 16

foci x^2-5y=0 foci

x^{2} - 5 y = 0

foci x^2+6x-1 foci

x^{2} + 6 x - 1

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

y = - (x + 3)^{2} - 1

foci y=x^2+8x-5 foci

y = x^{2} + 8 x - 5
