foci-9x^2

Solution

foci

- 9 x^{2}

Solution

(0, - \frac{1}{36})

Solution steps

Rewrite

y = - 9 x^{2}

in the standard form:

4 (- \frac{1}{36}) (y - 0) = (x - 0)^{2}

(h, k) = (0, 0), p = - \frac{1}{36}

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

p

from the center

(0, 0)

along the y-axis

(0, 0 + p)

= (0, 0 + (- \frac{1}{36}))

Refine

(0, - \frac{1}{36})

foci 2y^2+8y+x+1=0 foci

2 y^{2} + 8 y + x + 1 = 0

foci x^2-4x-12 foci

x^{2} - 4 x - 12

foci+18500(0.09-x^2)foci

+ 18500 (0.09 - x^{2})

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

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