1/2 x=(y-1)/(x+3)

解答

\frac{1}{2} x = \frac{y - 1}{x + 3}

解答

(h, k) = (- \frac{3}{2}, - \frac{1}{8}), p = \frac{1}{2}

求解步骤

\frac{1}{2} x = \frac{y - 1}{x + 3}

将

\frac{1}{2} x - \frac{y - 1}{x + 3} = 0

改写为标准形式

4 \cdot \frac{1}{2} (y - (- \frac{1}{8})) = (x - (- \frac{3}{2}))^{2}

因此抛物线性质是:

(h, k) = (- \frac{3}{2}, - \frac{1}{8}), p = \frac{1}{2}

流行的例子

y \geq 2 x^{2} + 2 x - 3

solvefor x,4k(x)^2+6=5k(x)^2-4x+3

so l v e f or x, 4 k (x)^{2} + 6 = 5 k (x)^{2} - 4 x + 3

(x+2)^2=-8(y-2)

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

- f (x) = x^{2} + x

(- x^{2}) - y = 0
