foci 9-x^2

Solution

foci

9 - x^{2}

Solution

(0, \frac{35}{4})

Solution steps

Rewrite

y = 9 - x^{2}

in the standard form:

4 (- \frac{1}{4}) (y - 9) = (x - 0)^{2}

(h, k) = (0, 9), p = - \frac{1}{4}

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

p

from the center

(0, 9)

along the y-axis

(0, 9 + p)

= (0, 9 + (- \frac{1}{4}))

Refine

(0, \frac{35}{4})

Popular Examples

foci+(5x-1)^2 foci

+ (5 x - 1)^{2}

foci y=x^2+2x+12 foci

y = x^{2} + 2 x + 12

foci x=(y+4)^2 foci

x = (y + 4)^{2}

foci y=6x^2-1 foci

y = 6 x^{2} - 1

foci 1.5+17.67t-4.905t^2 foci

1.5 + 17.67 t - 4.905 t^{2}
