foki 4(x+2)^2+5

Lösung

foki

4 (x + 2)^{2} + 5

Lösung

(- 2, \frac{81}{16})

Schritte zur Lösung

Rewrite

y = 4 (x + 2)^{2} + 5

in the standard form:

4 \cdot \frac{1}{16} (y - 5) = (x - (- 2))^{2}

(h, k) = (- 2, 5), p = \frac{1}{16}

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

p

from the center

(- 2, 5)

along the y-axis

(- 2, 5 + p)

= (- 2, 5 + \frac{1}{16})

Fasse zusammen
