y+3=-1/4 (x-7)^2

Lösung

y + 3 = - \frac{1}{4} (x - 7)^{2}

(h, k) = (7, - 3), p = - 1

Schritte zur Lösung

y + 3 = - \frac{1}{4} (x - 7)^{2}

Rewrite

y + 3 = - \frac{1}{4} (x - 7)^{2}

in the standard form:

4 (- 1) (y - (- 3)) = (x - 7)^{2}

Therefore parabola properties are:

(h, k) = (7, - 3), p = - 1

(x + 1)^{2} = - 8 (y + 1)

(x + 4)^{2} = - 8 (y - 1)

y - 5 = - 7 x (x - 1)

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

x^{2} + 2 y = 7
