foci y=+4-x^2

Solution

foci

y = + 4 - x^{2}

Solution

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

Solution steps

Rewrite

y = 4 - x^{2}

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=(9x^2)/2 foci

y = \frac{9 x ^{2}}{2}

foci-(x+1)^2+4 foci

- (x + 1)^{2} + 4

foci (x-4)^2=8(y+2)foci

(x - 4)^{2} = 8 (y + 2)

foci (x+2)^2=-12(y+2)foci

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

foci y= 1/64 s^2 foci

y = \frac{1}{64} s^{2}
