foci-2x^2+3x-1

Solution

foci

- 2 x^{2} + 3 x - 1

Solution

(\frac{3}{4}, 0)

Solution steps

Rewrite

y = - 2 x^{2} + 3 x - 1

in the standard form

4 (- \frac{1}{8}) (y - \frac{1}{8}) = (x - \frac{3}{4})^{2}

(h, k) = (\frac{3}{4}, \frac{1}{8}), p = - \frac{1}{8}

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

p

from the center

(\frac{3}{4}, \frac{1}{8})

along the y-axis

(\frac{3}{4}, \frac{1}{8} + p)

= (\frac{3}{4}, \frac{1}{8} + (- \frac{1}{8}))

Refine

(\frac{3}{4}, 0)

foci x^2-2x+8y+9=0 foci

x^{2} - 2 x + 8 y + 9 = 0

foci 2x^2+1 foci

2 x^{2} + 1

foci t^2-10t+25 foci

t^{2} - 10 t + 25

foci y=6x^2 foci

y = 6 x^{2}
