foci-x^2-3

Solution

foci

- x^{2} - 3

Solution

(0, - \frac{13}{4})

Solution steps

Rewrite

y = - x^{2} - 3

in the standard form:

4 (- \frac{1}{4}) (y - (- 3)) = (x - 0)^{2}

(h, k) = (0, - 3), p = - \frac{1}{4}

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

p

from the center

(0, - 3)

along the y-axis

(0, - 3 + p)

= (0, - 3 + (- \frac{1}{4}))

Refine

(0, - \frac{13}{4})

Popular Examples

foci x^2-4x-12y-20=0 foci

x^{2} - 4 x - 12 y - 20 = 0

foci-2x^2+6x foci

- 2 x^{2} + 6 x

foci y=x^2+2x+1 foci

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

foci x=3(y-2)^2-7 foci

x = 3 (y - 2)^{2} - 7

foci 3x^2+2x+6 foci

3 x^{2} + 2 x + 6
