c=100q^2-20000q+1500000

解

c = 100 q^{2} - 20000 q + 1500000

(h, k) = (500000, 100), p = \frac{1}{400}

解答ステップ

c = 100 q^{2} - 20000 q + 1500000

c = 100 q^{2} - 20000 q + 1500000

を標準的な形式で書き換える

4 \cdot \frac{1}{400} (c - 500000) = (q - 100)^{2}

ゆえに放物線の特性は:

(h, k) = (500000, 100), p = \frac{1}{400}
