foci-x^2+4

Solution

foci

- x^{2} + 4

Solution

(0, \frac{15}{4})

Solution steps

Rewrite

y = - x^{2} + 4

in the standard form:

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

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

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

p

from the center

(0, 4)

along the y-axis

(0, 4 + p)

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

Refine

(0, \frac{15}{4})

Popular Examples

foci y=7x^2 foci

y = 7 x^{2}

foci y=x^2+2x+4 foci

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

foci y^2+2y+1=-2x+4 foci

y^{2} + 2 y + 1 = - 2 x + 4

foci (y-3)^2=-8(x+2)foci

(y - 3)^{2} = - 8 (x + 2)

foci y=+x^2+6x foci

y = + x^{2} + 6 x
