foci y=x^2-2x-9

Solution

foci

y = x^{2} - 2 x - 9

Solution

(1, - \frac{39}{4})

Solution steps

Rewrite

y = x^{2} - 2 x - 9

in the standard form

4 \cdot \frac{1}{4} (y - (- 10)) = (x - 1)^{2}

(h, k) = (1, - 10), p = \frac{1}{4}

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

p

from the center

(1, - 10)

along the y-axis

(1, - 10 + p)

= (1, - 10 + \frac{1}{4})

Refine

(1, - \frac{39}{4})

Popular Examples

foci y=x^2-2x-5 foci

y = x^{2} - 2 x - 5

foci x^2-10x-20y=-185 foci

x^{2} - 10 x - 20 y = - 185

foci x=-y^2 foci

x = - y^{2}

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

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

foci-2x^2+4x+3 foci

- 2 x^{2} + 4 x + 3
