foci-x^2+6x-9

Solution

foci

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})
