foci-2x^2+4x+7

Solution

foci

- 2 x^{2} + 4 x + 7

Solution

(1, \frac{71}{8})

Solution steps

Rewrite

y = - 2 x^{2} + 4 x + 7

in the standard form

4 (- \frac{1}{8}) (y - 9) = (x - 1)^{2}

(h, k) = (1, 9), p = - \frac{1}{8}

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

p

from the center

(1, 9)

along the y-axis

(1, 9 + p)

= (1, 9 + (- \frac{1}{8}))

Refine

(1, \frac{71}{8})

Popular Examples

foci-2x^2+4x-7 foci

- 2 x^{2} + 4 x - 7

foci 6y=x^2-8x+14 foci

6 y = x^{2} - 8 x + 14

foci (x-1)^2=-8(y2)foci

(x - 1)^{2} = - 8 (y 2)

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

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

- 4 x^{2}
