foki x^2-2x-15

Lösung

foki

x^{2} - 2 x - 15

Lösung

(1, - \frac{63}{4})

Schritte zur Lösung

Rewrite

y = x^{2} - 2 x - 15

in the standard form

4 \cdot \frac{1}{4} (y - (- 16)) = (x - 1)^{2}

(h, k) = (1, - 16), p = \frac{1}{4}

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

p

from the center

(1, - 16)

along the y-axis

(1, - 16 + p)

= (1, - 16 + \frac{1}{4})

Fasse zusammen
