foci+2x^2-3x-1

Solution

foci

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

Solution

(\frac{3}{4}, - 2)

Solution steps

Rewrite

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

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{17}{8})) = (x - \frac{3}{4})^{2}

(h, k) = (\frac{3}{4}, - \frac{17}{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{17}{8})

along the y-axis

(\frac{3}{4}, - \frac{17}{8} + p)

= (\frac{3}{4}, - \frac{17}{8} + \frac{1}{8})

Refine

(\frac{3}{4}, - 2)

Popular Examples

foci y= 1/2 x^2-2 foci

y = \frac{1}{2} x^{2} - 2

foci 2x^2-5x+1 foci

2 x^{2} - 5 x + 1

foci-x^2-6x-8 foci

- x^{2} - 6 x - 8

foci-16x^2+136x+57 foci

- 16 x^{2} + 136 x + 57

foci 2x=-y^2 foci

2 x = - y^{2}
