foci x^2-1

Solution

foci

x^{2} - 1

Solution

(0, - \frac{3}{4})

Solution steps

Rewrite

y = x^{2} - 1

in the standard form:

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

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

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

p

from the center

(0, - 1)

along the y-axis

(0, - 1 + p)

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

Refine

(0, - \frac{3}{4})

Popular Examples

foci y=x^2-4x foci

y = x^{2} - 4 x

foci x^2-6x+5y=-34 foci

x^{2} - 6 x + 5 y = - 34

foci 5x(2x+4)-3x foci

5 x (2 x + 4) - 3 x

foci x^2-10x-12y-23=0 foci

x^{2} - 10 x - 12 y - 23 = 0

foci y=(9x-2)x3 foci

y = (9 x - 2) x 3
