foci x^2+9x-8

Solution

foci

x^{2} + 9 x - 8

Solution

(- \frac{9}{2}, - 28)

Solution steps

Rewrite

y = x^{2} + 9 x - 8

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{113}{4})) = (x - (- \frac{9}{2}))^{2}

(h, k) = (- \frac{9}{2}, - \frac{113}{4}), p = \frac{1}{4}

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

p

from the center

(- \frac{9}{2}, - \frac{113}{4})

along the y-axis

(- \frac{9}{2}, - \frac{113}{4} + p)

= (- \frac{9}{2}, - \frac{113}{4} + \frac{1}{4})

Refine

(- \frac{9}{2}, - 28)

Popular Examples

foci y= 1/20 x^2 foci

y = \frac{1}{20} x^{2}

foci x^2-2x-1 foci

x^{2} - 2 x - 1

foci 3y^2+12x=0 foci

3 y^{2} + 12 x = 0

foci 3x^2+4 foci

3 x^{2} + 4

foci 3x^2+1 foci

3 x^{2} + 1
