x=(ay^2)/2

解答

x = \frac{a y ^{2}}{2}

(h, k) = (0, 0), p = \frac{1}{2 a}

求解步骤

x = \frac{a y ^{2}}{2}

将

x = \frac{a y ^{2}}{2}

改写为标准形式:

4 \cdot \frac{1}{2 a} (x - 0) = (y - 0)^{2}

因此抛物线性质是:

(h, k) = (0, 0), p = \frac{1}{2 a}

18 x^{2} + \frac{1}{6} r (x) = 10

\frac{3 y ^{(2)} - 30 y + 2 x + ( 101 )}{( 2 )} = 0

(y + 2)^{2} = 20 (x - 3)

(x + 3)^{2} = 12 (y + 5)

y - 5 x^{2} = 2 x - 6
