foci x^2+8x+18

Solution

foci

x^{2} + 8 x + 18

Solution

(- 4, \frac{9}{4})

Solution steps

Rewrite

y = x^{2} + 8 x + 18

in the standard form

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

(h, k) = (- 4, 2), p = \frac{1}{4}

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

p

from the center

(- 4, 2)

along the y-axis

(- 4, 2 + p)

= (- 4, 2 + \frac{1}{4})

Refine

(- 4, \frac{9}{4})

Popular Examples

foci x^2+8x+15 foci

x^{2} + 8 x + 15

foci (y-4)^2=-8(x+1)foci

(y - 4)^{2} = - 8 (x + 1)

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

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

foci x^2=-6(y-7)foci

x^{2} = - 6 (y - 7)

foci 2y^2=16x foci

2 y^{2} = 16 x
