y^2-x=8

解答

y^{2} - x = 8

(h, k) = (- 8, 0), p = \frac{1}{4}

求解步骤

y^{2} - x = 8

将

y^{2} - x = 8

改写为标准形式:

4 \cdot \frac{1}{4} (x - (- 8)) = (y - 0)^{2}

因此抛物线性质是:

(h, k) = (- 8, 0), p = \frac{1}{4}

so l v e f or f, f (x)^{2} (2) = 4 x + 5

2 x - 7 = y (x, y) a y (4.1)

\frac{x}{2} x + 8 y = 8

(y + \frac{3}{4})^{2} = 2 (x + \frac{33}{32})

x = 2 \cdot y - y^{2}
