(c^2<= α^2)*(-1)

解

(c^{2} \leq α^{2}) \cdot (- 1)

(h, k) = (0, - \frac{0}{- = c ^{2}}), p = \frac{1}{4 ( \frac{1}{- = c ^{2}} )}

解答ステップ

y = c^{2} \leq α^{2} (- 1)

y = c^{2} \leq α^{2} (- 1)

を標準的な形式で書き換える:

4 \cdot \frac{1}{4 ( \frac{1}{- = c ^{2}} )} (y - (- \frac{0}{- = c ^{2}})) = (α - 0)^{2}

ゆえに放物線の特性は:

(h, k) = (0, - \frac{0}{- = c ^{2}}), p = \frac{1}{4 ( \frac{1}{- = c ^{2}} )}
