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 (- \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^2-6x+15 foci

- x^{2} - 6 x + 15

foci-3x^2-2 foci

- 3 x^{2} - 2

foci (x+1)^2=-12(y-6)foci

(x + 1)^{2} = - 12 (y - 6)

foci (x-4)^2=-8(y+4)foci

(x - 4)^{2} = - 8 (y + 4)

foci (y-5)^2-4 foci

(y - 5)^{2} - 4
