foci s^2+4s+20

Solution

foci

s^{2} + 4 s + 20

Solution

(- 2, \frac{65}{4})

Solution steps

Rewrite

y = s^{2} + 4 s + 20

in the standard form

4 \cdot \frac{1}{4} (y - 16) = (s - (- 2))^{2}

(h, k) = (- 2, 16), p = \frac{1}{4}

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

p

from the center

(- 2, 16)

along the y-axis

(- 2, 16 + p)

= (- 2, 16 + \frac{1}{4})

Refine

(- 2, \frac{65}{4})

Popular Examples

foci y=x^2+5x+6 foci

y = x^{2} + 5 x + 6

foci x^2+3x-4 foci

x^{2} + 3 x - 4

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

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

foci (x+3)^2=24(y-1)foci

(x + 3)^{2} = 24 (y - 1)

foci 3-2x-x^2 foci

3 - 2 x - x^{2}
