foci 2x^2-4x-5

Solution

foci

2 x^{2} - 4 x - 5

Solution

(1, - \frac{55}{8})

Solution steps

Rewrite

y = 2 x^{2} - 4 x - 5

in the standard form

4 \cdot \frac{1}{8} (y - (- 7)) = (x - 1)^{2}

(h, k) = (1, - 7), p = \frac{1}{8}

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

p

from the center

(1, - 7)

along the y-axis

(1, - 7 + p)

= (1, - 7 + \frac{1}{8})

Refine

(1, - \frac{55}{8})

Popular Examples

foci 5x^2-40x+4y+85=0 foci

5 x^{2} - 40 x + 4 y + 85 = 0

foci x^2-3x+10 foci

x^{2} - 3 x + 10

foci y=+x^2-x foci

y = + x^{2} - x

foci x^2+8x-16 foci

x^{2} + 8 x - 16

foci y=+3x^2+24x-51 foci

y = + 3 x^{2} + 24 x - 51
