foci x^2-4x-5

Solution

foci

x^{2} - 4 x - 5

Solution

(2, - \frac{35}{4})

Solution steps

Rewrite

y = x^{2} - 4 x - 5

in the standard form

4 \cdot \frac{1}{4} (y - (- 9)) = (x - 2)^{2}

(h, k) = (2, - 9), p = \frac{1}{4}

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

p

from the center

(2, - 9)

along the y-axis

(2, - 9 + p)

= (2, - 9 + \frac{1}{4})

Refine

(2, - \frac{35}{4})

Popular Examples

foci y=-2(x-3)^2+1 foci

y = - 2 (x - 3)^{2} + 1

foci x^2+4x-8y+12=0 foci

x^{2} + 4 x - 8 y + 12 = 0

foci y=x^2+x+1 foci

y = x^{2} + x + 1

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

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

foci y=x^2-2x^2 foci

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