foci-3x^2-2

Solution

foci

- 3 x^{2} - 2

Solution

(0, - \frac{25}{12})

Solution steps

Rewrite

y = - 3 x^{2} - 2

in the standard form:

4 (- \frac{1}{12}) (y - (- 2)) = (x - 0)^{2}

(h, k) = (0, - 2), p = - \frac{1}{12}

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

p

from the center

(0, - 2)

along the y-axis

(0, - 2 + p)

= (0, - 2 + (- \frac{1}{12}))

Refine

(0, - \frac{25}{12})

Popular Examples

foci (x+1)^2=-12(y-6)foci

(x + 1)^{2} = - 12 (y - 6)

foci (x-4)^2=-8(y+4)foci

(x - 4)^{2} = - 8 (y + 4)

foci (y-5)^2-4 foci

(y - 5)^{2} - 4

foci-x^2=48y foci

- x^{2} = 48 y

foci 3x^2+x-6 foci

3 x^{2} + x - 6
