foki-(x+1)^2+4

Lösung

foki

- (x + 1)^{2} + 4

Lösung

(- 1, \frac{15}{4})

Schritte zur Lösung

Rewrite

y = - (x + 1)^{2} + 4

in the standard form:

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

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

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

p

from the center

(- 1, 4)

along the y-axis

(- 1, 4 + p)

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

Fasse zusammen
