foci y=(x^2-4)/2

Solution

foci

y = \frac{x ^{2} - 4}{2}

Solution

(0, - \frac{3}{2})

Solution steps

Rewrite

y = \frac{x ^{2} - 4}{2}

in the standard form

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

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

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}{2})

Refine

(0, - \frac{3}{2})

Popular Examples

foci x=(y+1)^2-4 foci

x = (y + 1)^{2} - 4

foci (y-2)^2=12(x-3)foci

(y - 2)^{2} = 12 (x - 3)

foci x^2+14x+48 foci

x^{2} + 14 x + 48

foci 2x^2+7x-4 foci

2 x^{2} + 7 x - 4

foci x^2+14x+26 foci

x^{2} + 14 x + 26
