foci x(x+1)

Solution

foci

x (x + 1)

Solution

(- \frac{1}{2}, 0)

Solution steps

Rewrite

y = x (x + 1)

in the standard form

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

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

along the y-axis

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

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

Refine

(- \frac{1}{2}, 0)

Popular Examples

foci y=0.00225x^2+5999.9325x+0.50625 foci

y = 0.00225 x^{2} + 5999.9325 x + 0.50625

foci 2(x-2)^2 foci

2 (x - 2)^{2}

foci x=7y^2 foci

x = 7 y^{2}

foci x^2+12y=0 foci

x^{2} + 12 y = 0

X^{2}
