foci x^2+2x+4

Solution

foci

x^{2} + 2 x + 4

Solution

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

Solution steps

Rewrite

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

in the standard form

4 \cdot \frac{1}{4} (y - 3) = (x - (- 1))^{2}

(h, k) = (- 1, 3), p = \frac{1}{4}

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

p

from the center

(- 1, 3)

along the y-axis

(- 1, 3 + p)

= (- 1, 3 + \frac{1}{4})

Refine

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

Popular Examples

foci y=3-x^2 foci

y = 3 - x^{2}

foci x^2=10y foci

x^{2} = 10 y

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

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

foci x(x+1)foci

x (x + 1)

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

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