(y-(15))^2=2(x-1)

解答

(y - (15))^{2} = 2 (x - 1)

解答

(h, k) = (1, 15), p = \frac{1}{2}

求解步骤

(y - 15)^{2} = 2 (x - 1)

将

(y - 15)^{2} = 2 (x - 1)

改写为标准形式:

4 \cdot \frac{1}{2} (x - 1) = (y - 15)^{2}

因此抛物线性质是:

(h, k) = (1, 15), p = \frac{1}{2}

流行的例子

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

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

(y-1)^2=12(x+4)

(y - 1)^{2} = 12 (x + 4)

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

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

y^{2} + 2 x - 4 y - 4 = 0
