foci-2x^2

Solution

foci

- 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

x^{2} + y = 4

vertices f(x)=-x^2+4 vertices

f (x) = - x^{2} + 4

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

3x^2-8y^2+12x+16y+20=0

3 x^{2} - 8 y^{2} + 12 x + 16 y + 20 = 0

vertices f(x)=-3x^2+6x-1 vertices

f (x) = - 3 x^{2} + 6 x - 1
