foki-x^2+3x-5

Lösung

foki

- x^{2} + 3 x - 5

Lösung

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

Schritte zur Lösung

Rewrite

y = - x^{2} + 3 x - 5

in the standard form

4 (- \frac{1}{4}) (y - (- \frac{11}{4})) = (x - \frac{3}{2})^{2}

(h, k) = (\frac{3}{2}, - \frac{11}{4}), p = - \frac{1}{4}

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

p

from the center

(\frac{3}{2}, - \frac{11}{4})

along the y-axis

(\frac{3}{2}, - \frac{11}{4} + p)

= (\frac{3}{2}, - \frac{11}{4} + (- \frac{1}{4}))
