foci 2x^2-4x+9

Solution

foci

2 x^{2} - 4 x + 9

Solution

(1, \frac{57}{8})

Solution steps

Rewrite

y = 2 x^{2} - 4 x + 9

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{57}{8})

Popular Examples

foci y=5x^2+210x-34775 foci

y = 5 x^{2} + 210 x - 34775

foci y^2-x=0 foci

y^{2} - x = 0

foci y^2+28x=0 foci

y^{2} + 28 x = 0

foci y^2+12x+4y-32=0 foci

y^{2} + 12 x + 4 y - 32 = 0

foci y=(5-x)(2x-3)foci

y = (5 - x) (2 x - 3)
