foci y=x^2-7

Solution

foci

y = x^{2} - 7

Solution

(0, - \frac{27}{4})

Solution steps

Rewrite

y = x^{2} - 7

in the standard form:

4 \cdot \frac{1}{4} (y - (- 7)) = (x - 0)^{2}

(h, k) = (0, - 7), p = \frac{1}{4}

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

p

from the center

(0, - 7)

along the y-axis

(0, - 7 + p)

= (0, - 7 + \frac{1}{4})

Refine

(0, - \frac{27}{4})

Popular Examples

foci x^2=24y foci

x^{2} = 24 y

foci 2x^2+3x-20 foci

2 x^{2} + 3 x - 20

foci x+7= 1/36 (y+3)^2 foci

x + 7 = \frac{1}{36} (y + 3)^{2}

foci 2y^2-8x=0 foci

2 y^{2} - 8 x = 0

foci y^2-8y+4x=0 foci

y^{2} - 8 y + 4 x = 0
