foci-3x^2-x+4

Solution

foci

- 3 x^{2} - x + 4

Solution

(- \frac{1}{6}, 4)

Solution steps

Rewrite

y = - 3 x^{2} - x + 4

in the standard form

4 (- \frac{1}{12}) (y - \frac{49}{12}) = (x - (- \frac{1}{6}))^{2}

(h, k) = (- \frac{1}{6}, \frac{49}{12}), p = - \frac{1}{12}

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

p

from the center

(- \frac{1}{6}, \frac{49}{12})

along the y-axis

(- \frac{1}{6}, \frac{49}{12} + p)

= (- \frac{1}{6}, \frac{49}{12} + (- \frac{1}{12}))

Refine

(- \frac{1}{6}, 4)

Popular Examples

foci y=((-6(r+4r^2)+9r^2+6r)^2)/(9r^2)foci

y = \frac{( - 6 ( r + 4 r ^{2} ) + 9 r ^{2} + 6 r ) ^{2}}{9 r ^{2}}

foci y^2+2y-4x+9=0 foci

y^{2} + 2 y - 4 x + 9 = 0

foci (x-5)(x+2)foci

(x - 5) (x + 2)

foci (x+1)^2+3 foci

(x + 1)^{2} + 3

foci y^2+2y+12x+25=0 foci

y^{2} + 2 y + 12 x + 25 = 0
