foci 3-2x-x^2

Solution

foci

3 - 2 x - x^{2}

Solution

(- 1, \frac{15}{4})

Solution steps

Rewrite

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

in the standard form

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

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

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

p

from the center

(- 1, 4)

along the y-axis

(- 1, 4 + p)

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

Refine

(- 1, \frac{15}{4})

Popular Examples

foci x^2+x-1 foci

x^{2} + x - 1

foci y=-x^2+2 foci

y = - x^{2} + 2

foci (y-5)^2=12(x+3)foci

(y - 5)^{2} = 12 (x + 3)

foci y=2x^2+16x+29 foci

y = 2 x^{2} + 16 x + 29

foci y=(x+5)^2 foci

y = (x + 5)^{2}
