-(y+1)=(x-2)^2

Lösung

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

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

Schritte zur Lösung

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

Rewrite

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

in the standard form:

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

Therefore parabola properties are:

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

z 20 z - 4 y + 77 = - 15

3 x^{2} = 6 + 2 y

x = y^{2} - 5 y

x = y^{2} - 16

- x^{2} + y \geq 1
