foci x^2+9x+18

Solution

foci

x^{2} + 9 x + 18

Solution

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

Solution steps

Rewrite

y = x^{2} + 9 x + 18

in the standard form

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

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

along the y-axis

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

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

Refine

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

x = 6 y^{2}

foci 2250(0.015-0.001x)^2+6000x foci

2250 (0.015 - 0.001 x)^{2} + 6000 x

foci x^2*3 foci

x^{2} \cdot 3

foci x=y^2-4y+1 foci

x = y^{2} - 4 y + 1

foci (-3x^2-2x+6)/5 foci

\frac{- 3 x ^{2} - 2 x + 6}{5}
