foci x^2+2x-2

Solution

foci

x^{2} + 2 x - 2

Solution

(- 1, - \frac{11}{4})

Solution steps

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - (- 3)) = (x - (- 1))^{2}

(h, k) = (- 1, - 3), p = \frac{1}{4}

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

p

from the center

(- 1, - 3)

along the y-axis

(- 1, - 3 + p)

= (- 1, - 3 + \frac{1}{4})

Refine

(- 1, - \frac{11}{4})

Popular Examples

foci 2y^2=3x foci

2 y^{2} = 3 x

foci (y+5)^2=-12(x+1)foci

(y + 5)^{2} = - 12 (x + 1)

foci (x-3)^2=-8(y+2)foci

(x - 3)^{2} = - 8 (y + 2)

foci (x+3)^2=8(y-2)foci

(x + 3)^{2} = 8 (y - 2)

foci y=-3x^2+30x-71 foci

y = - 3 x^{2} + 30 x - 71
