foci 2(x+1)^2

Solution

foci

2 (x + 1)^{2}

Solution

(- 1, \frac{1}{8})

Solution steps

Rewrite

y = 2 (x + 1)^{2}

in the standard form:

4 \cdot \frac{1}{8} (y - 0) = (x - (- 1))^{2}

(h, k) = (- 1, 0), p = \frac{1}{8}

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

p

from the center

(- 1, 0)

along the y-axis

(- 1, 0 + p)

= (- 1, 0 + \frac{1}{8})

Refine

(- 1, \frac{1}{8})

(x + 3)^{2} = - 12 (y - 5)

foci-2x^2+20x-52 foci

- 2 x^{2} + 20 x - 52

foci x^2+6x+9 foci

x^{2} + 6 x + 9

foci+x^2+8x-80 foci

+ x^{2} + 8 x - 80

foci x^2+5y=14x+11 foci

x^{2} + 5 y = 14 x + 11
