foci y=-x^2

Solution

foci

y = - x^{2}

Solution

(0, - \frac{1}{4})

Solution steps

Rewrite

y = - x^{2}

in the standard form:

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

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

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}{4}))

Refine

(0, - \frac{1}{4})

Popular Examples

foci y=-1/4 x^2+8x-4 foci

y = - \frac{1}{4} x^{2} + 8 x - 4

foci t^2-t-14 foci

t^{2} - t - 14

foci 2x^2+5x-7 foci

2 x^{2} + 5 x - 7

foci y=2x^2-19x+9 foci

y = 2 x^{2} - 19 x + 9

foci y=x^2-16 foci

y = x^{2} - 16
