foci y=-2x^2

Solution

foci

y = - 2 x^{2}

Solution

(0, - \frac{1}{8})

Solution steps

Rewrite

y = - 2 x^{2}

in the standard form:

4 (- \frac{1}{8}) (y - 0) = (x - 0)^{2}

(h, k) = (0, 0), p = - \frac{1}{8}

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}{8}))

Refine

(0, - \frac{1}{8})

Popular Examples

foci y=+1/7 x^2 foci

y = + \frac{1}{7} x^{2}

foci y=2x^2+x-15 foci

y = 2 x^{2} + x - 15

foci x=y^2+4y+10 foci

x = y^{2} + 4 y + 10

foci (x+7)^2=-12(y-7)foci

(x + 7)^{2} = - 12 (y - 7)

foci 3y^2=-4x foci

3 y^{2} = - 4 x
