foci-2x^2+8x

Solution

foci

- 2 x^{2} + 8 x

Solution

(2, \frac{63}{8})

Solution steps

Rewrite

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

in the standard form

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

(h, k) = (2, 8), p = - \frac{1}{8}

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

p

from the center

(2, 8)

along the y-axis

(2, 8 + p)

= (2, 8 + (- \frac{1}{8}))

Refine

(2, \frac{63}{8})

Popular Examples

foci y^2=(25)/(-2)x foci

y^{2} = \frac{25}{- 2} x

foci-x^2-3 foci

- x^{2} - 3

foci x^2-4x-12y-20=0 foci

x^{2} - 4 x - 12 y - 20 = 0

foci-2x^2+6x foci

- 2 x^{2} + 6 x

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

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