foci x^2-2x-3

Solution

foci

x^{2} - 2 x - 3

Solution

(1, - \frac{15}{4})

Solution steps

Rewrite

y = x^{2} - 2 x - 3

in the standard form

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

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

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

p

from the center

(1, - 4)

along the y-axis

(1, - 4 + p)

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

Refine

(1, - \frac{15}{4})

Popular Examples

foci x^2+8x+18 foci

x^{2} + 8 x + 18

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)
