foci-x^2-x+3

Solution

foci

- x^{2} - x + 3

Solution

(- \frac{1}{2}, 3)

Solution steps

Rewrite

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

in the standard form

4 (- \frac{1}{4}) (y - \frac{13}{4}) = (x - (- \frac{1}{2}))^{2}

(h, k) = (- \frac{1}{2}, \frac{13}{4}), p = - \frac{1}{4}

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

p

from the center

(- \frac{1}{2}, \frac{13}{4})

along the y-axis

(- \frac{1}{2}, \frac{13}{4} + p)

= (- \frac{1}{2}, \frac{13}{4} + (- \frac{1}{4}))

Refine

(- \frac{1}{2}, 3)

Popular Examples

foci x^2+x-9 foci

x^{2} + x - 9

foci 5x^2+7 foci

5 x^{2} + 7

foci 5x^2+4 foci

5 x^{2} + 4

foci 3y^2=16x foci

3 y^{2} = 16 x

foci 9x^2+24x+72y+16=0 foci

9 x^{2} + 24 x + 72 y + 16 = 0
