foci x^2+6x+9

Solution

foci

x^{2} + 6 x + 9

Solution

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

Solution steps

Rewrite

y = x^{2} + 6 x + 9

in the standard form

4 \cdot \frac{1}{4} (y - 0) = (x - (- 3))^{2}

(h, k) = (- 3, 0), p = \frac{1}{4}

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

p

from the center

(- 3, 0)

along the y-axis

(- 3, 0 + p)

= (- 3, 0 + \frac{1}{4})

Refine

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

Popular Examples

foci+x^2+8x-80 foci

+ x^{2} + 8 x - 80

foci x^2+5y=14x+11 foci

x^{2} + 5 y = 14 x + 11

foci 4x^2+16x+36 foci

4 x^{2} + 16 x + 36

foci y=4x+4x-2+x^2-3 foci

y = 4 x + 4 x - 2 + x^{2} - 3

foci y=(x-5)^2-9 foci

y = (x - 5)^{2} - 9
